Dorchester (/ˈdɔːrtʃɛstər/) is a neighborhood comprising more than 6 square miles (16 km) in the City of Boston, Massachusetts, United States. Originally, Dorchester was a separate town, founded by Puritans who emigrated in 1630 from Dorchester, Dorset, England, to the Massachusetts Bay Colony. This dissolved municipality, Boston's largest neighborhood by far, is often divided by city planners in order to create two planning areas roughly equivalent in size and population to other Boston neighborhoods.

The neighborhood is named after the town of Dorchester in Dorset, from which Puritans emigrated to the New World on the ship Mary and John, among others.

Founded in 1630, just a few months before the founding of the city of Boston, Dorchester now covers a geographic area approximately equivalent to nearby Cambridge. When annexed to Boston in 1870, Dorchester was still a primarily rural town and had a population of 12,000. Construction of railroad and commuter streetcar lines brought rapid growth, increasing the population to 150,000 by 1920. In the 2010 United States Census, the neighborhood's population was 92,115.

The Dorchester neighborhood has a very diverse population, which includes a large concentration of African Americans, European Americans (particularly those of Irish, German, Italian, and Polish origin, reflecting late 19th and early 20th century immigration). More numerous immigrants and their descendants since the later 20th century have come from the Caribbean Caribbean, Central and South America, and East and Southeast Asian Americans.

Dorchester also has a significant LGBT population, with active political groups. It has the largest concentration of same-sex couples in Boston after the neighborhoods of South End and Jamaica Plain. Most of the people over the age of 25 have completed high school or obtained a GED.

Prior to European colonization, the region around Dorchester was inhabited by the indigenous Massachusett. They lived in settlements established alongside the Neponset River estuary, which was a plentiful source of fish, including trout; they also gathered shellfish from the riverbed, and hunted beaver and deer. They established farms in nearby hills. During the initial period of colonization by Puritan settlers, the Massachusett suffered a rapid decline in population due to the introduction of foreign infectious diseases to which they had no acquired immunity and violence related to settler colonialism.

The Massachusett sachem, Chickatawbut, negotiated land treaties with the Puritan settlers before dying of smallpox in 1633. His brother, Cutshamekin, who succeeded him, deeded further land to the settlers. The remaining Massachusett in the region, including Cutshamekin, accepted some Christianity as a form of survivance. They eventually resettled in the Praying Town of Natick.

In 1623 a syndicate of Dorsetshire fishermen organized an outport of fishing stages and flakes at Dorchester. In 1626 David Thompson settled his family on Thompson Island in what is now Dorchester before Boston's Puritan migration wave began in 1630.

On May 30, 1630, Captain Squib of the ship Mary and John entered Boston Harbor. On June 17, 1630, he landed a boat with eight men on the Dorchester shore, at what was then a narrow peninsula known as Mattapan or Mattaponnock. Today it is known as Columbia Point (more popularly since 1984 as Harbor Point). Those aboard the ship who founded the town included William Phelps, Roger Ludlowe, John Mason, John Maverick, Nicholas Upsall, Capt. Roger Fyler, William Gaylord, Henry Wolcott, and other men who would become prominent in the founding of a new nation. The original settlement founded in 1630 was at what is now the intersection of Columbia Road and Massachusetts Avenue. (Even though Dorchester was annexed more than 100 years ago into the city of Boston, residents still annually celebrate the founding on Dorchester Day. This includes festivities and a parade down Dorchester Avenue).

Most of the early Dorchester settlers came from the English West Country, and some from Dorchester, Dorset, where Rev. John White was chief proponent of a Puritan settlement in the Americas. The town developed around the First Parish Church of Dorchester. The building is now operated as the Unitarian-Universalist church on Meeting House Hill and is the oldest religious organization in present-day Boston.

On October 8, 1633, the first Town Meeting in what would become the United States was held in Dorchester. Today, October 8 is annually celebrated as Town Meeting Day in Massachusetts. Dorchester is the birthplace of the first public elementary school in America, the Mather School, established in 1639. The school still stands as the oldest elementary school in the United States. In 1634 Israel Stoughton built one of the earliest grist mills in America on the Neponset River; Richard Callicott founded a trading post nearby. In 1641, Dorcas ye blackmore, an enslaved servant to Israel Stoughton, was the first recorded African American to join a church in New England. She served as an evangelist to Stoughton's Native American servants, and the First Parish Church of Dorchester attempted to help Dorcas gain her freedom.

In 1649, Puritan missionaries, including John Eliot, began a campaign to convert the Indigenous people in Dorchester to Christianity with the help of Cockenoe and John Sassamon, two Indian servants in the town. Eliot was given land by the town of Dorchester for his mission, where he established a church and school.

The James Blake House, oldest surviving home in the city of Boston, is located at Edward Everett Square. This is the historic intersection of Columbia Road, Boston Street, and Massachusetts Avenue, a few blocks from the Dorchester Historical Society. The Blake House was constructed in 1661, as was confirmed by dendrochronology in 2007.

In 1695, a party was dispatched to found the town of Dorchester, South Carolina. It lasted a half-century before being abandoned.

In 1765, Irish chocolate maker John Hannon (or alternatively spelled "Hannan" in some sources) imported beans from the West Indies and refined them in Dorchester. He thus introduced chocolate to the North American colonies, and was working with Dr. James Baker, an American physician and investor. They opened America's first chocolate mill and factory in the Lower Mills section of Dorchester on the Neponset River. The Walter Baker Chocolate Factory, part of Walter Baker & Company, operated until 1965.

Before the American Revolution, "The Sons of Liberty met in August 1769 at the Lemuel Robinson Tavern, which stood on the east side of the upper road (Washington St.) near the present Fuller Street. Lemuel Robinson was a representative of the town during the Revolution and was appointed a colonel in the Revolutionary army." Dorchester (in a part of what is now South Boston) was also the site of the Battle of Dorchester Heights in 1776. As a result, the British evacuated Boston, pulling back to a base in New York's Manhattan and Long Island.

Originally part of Suffolk County, Massachusetts, the town of Dorchester removed from Suffolk County to Norfolk County when it was created on March 26, 1793. Portions of Dorchester annexed in the 19th century by Hyde Park, Milton or Quincy remained within Norfolk County. Portions annexed by Boston (eventually including Hyde Park) became part of Suffolk County again.

In Victorian times, Dorchester became a popular country retreat for Boston elite. It developed into a bedroom community, easily accessible to the city by streetcar for commuters. The mother and grandparents of John F. Kennedy lived in the Ashmont Hill neighborhood during the period that his grandfather John F. "Honey Fitz" Fitzgerald was mayor of Boston.

American poet Oliver Wendell Holmes, wrote a poem called "The Dorchester Giant" in 1830. He referred to the special kind of stone, "Roxbury puddingstone", quarried in Dorchester, which was used to build churches in the Boston area. Most notable of these is the Central Congregational Church (later called the Church of the Covenant) in Boston's Back Bay neighborhood.

In 1845, the Old Colony Railroad ran through the area and connected Boston and Plymouth, Massachusetts. The station was originally called Crescent Avenue or Crescent Avenue Depot as an Old Colony Railroad station. The name was changed to Columbia, which lasted until December 1, 1982.

It was then changed again, to JFK/UMASS. It is a Massachusetts Bay Transportation Authority rail line station for both the Red Line subway and the Plymouth/Kingston, Middleborough/Lakeville and Greenbush commuter rail lines.

In the 1840s and 1850s, a new wave of development took place on a strip of waterfront overlooking Dorchester Bay (Park and Mill streets at the Harrison Square Historic District, later known as Clam Point.) Renowned architects who contributed to one of the most significant and intact collections of Clam Point's Italianate mansards include Luther Briggs, John A. Fox, and Mary E. Noyes. By the 1890s, Clam Point gained prominence as a summer resort: the Russell House hotel was its centerpiece and the Dorchester Yacht Club was established on Freeport Street.

In the 1880s, the calf pasture on Columbia Point was developed for a Boston sewer line and pumping station. This large pumping station still stands. In its time it was a model for treating sewage and helping to promote cleaner and healthier urban living conditions. It pumped waste to a remote treatment facility on Moon Island in Boston Harbor, and served as a model for other systems worldwide. This system was operated as the Boston Sewer system's headworks, handling all of the city's sewage, until 1968.

At that time a new treatment facility was built on Deer Island. The pumping station is architecturally significant as a Richardsonian Romanesque designed by Boston City architect, George Clough.The only remaining 19th-century building on Columbia Point, the headworks is listed on the National Register of Historic Places.

Dorchester was annexed by Boston in pieces beginning on March 6, 1804, and ending with complete annexation to the city of Boston after a plebiscite was held in Boston and Dorchester on June 22, 1869. As a result, Dorchester officially became part of Boston on January 3, 1870. This is the historic reason that Dorchester Heights is today considered part of South Boston, not modern-day Dorchester. It was part of the earliest cession of Dorchester to Boston in 1804. Additional parts of Dorchester were ceded to Quincy (in 1792, 1814, 1819, and 1855). Portions of the original town of Dorchester developed as the separate towns of Hyde Park (1868 and later annexed to Boston in 1912), Milton (1662), and Stoughton (1726, itself later subdivided).

In 1895, Frederick Law Olmsted, architect of the Boston Public Garden/Emerald Necklace in Boston and Central Park in New York City, was commissioned to create Dorchester Park. It was intended as an urban forest for the residents of a growing Dorchester.

In 1904, the Dorchester Historical Society incorporated "Dorchester Day", which commemorated the settlement of Dorchester in 1630. Celebrated annually, Dorchester Day is a tableau of community events, highlighted by such activities as the Landing Day Observance, the Dorchester Day Parade along Dorchester Avenue the first Sunday in June, and the Community Banquet.

During the late 19th and early 20th centuries, Dorchester was a site for community activism related to diverse issues. The first racially integrated neighborhood developed on Jones Hill. One of the residents of that neighborhood, William Monroe Trotter, with W.E.B. Du Bois, helped to found the Niagara Movement, the precursor of the National Association for the Advancement of Colored People. Many leading suffragettes also lived in Dorchester, including Lucy Stone.

In the early 20th century, Dorchester received numerous Catholic immigrants from a variety of nations, such as Ireland, French Canada, Italy, and Poland. In addition, it was a destination for thousands of mostly Protestant African Americans from the South who were making the Great Migration to northern industrial cities for work opportunities and to escape Jim Crow violence. Numerous three-decker apartment buildings were built in Dorchester to house the many industrial workers.

In the early 1950s, Dorchester became a center of civil rights activism by African Americans, who were constrained by de facto segregation in Boston. Martin Luther King Jr. lived there for much of the time he attended Boston University for his PhD.

"With Boston's Baptist community riveted by his preaching and Coretta [Scott King] at his side, King's circle grew. The Dorchester apartment drew friends and followers like a magnet, according to [friend and roommate John] Bustamante, with 'untold numbers of visitors coming from the other schools.' The roommates housed and fed the visitors, who would join in civil rights discussions."

During the 1960s–1980s, the ethnic landscape of Dorchester changed dramatically. The descendants of early 20th-century Jewish, Italian, and Irish immigrants had become more established and generally moved to newer housing in the suburbs. Newer African, Asian, and Caribbean immigrants and their descendants settled here in the older housing in a succession of ethnicities.

The first community health center in the United States was the Columbia Point Health Center in Dorchester. It was opened in December 1965 and served mostly the massive Columbia Point public housing complex adjoining it. It was founded by two medical doctors, Jack Geiger, who had been on the faculty of Harvard University and later at Tufts University; and Count Gibson from Tufts University.

Geiger had previously studied the first community health centers and the principles of Community Oriented Primary Care with Sidney Kark and colleagues while serving as a medical student in rural Natal, South Africa.

The Columbia Point Health Center is still operating and was rededicated in 1990 as the Geiger-Gibson Community Health Center.

In 1974, the University of Massachusetts Boston moved from Park Square in downtown Boston to Columbia Point in Dorchester. In 1982, Boston State College was incorporated into UMass Boston. Since the 1970s, UMass Boston has expanded substantially, including building a new campus center in 2004 and a new science center in 2015. It has also hosted numerous important social and civic events. In 2000, for example, the university hosted a presidential candidates’ debate between George W. Bush and Al Gore.

In 1977, after an unsuccessful bid by Cambridge to have the John F. Kennedy Library located there, close to the late president's alma mater Harvard University, a site was chosen at the tip of Columbia Point and ground was broken. Designed by architect I. M. Pei, the John F. Kennedy Presidential Library and Museum was dedicated on October 20, 1979.

By the 1980s, the Blue Hill Avenue section of Dorchester had become a predominantly Black community.

During the 1990s, the city administration increased police presence and invested city money into the area for more street lighting.

On March 30, 2015, the Edward M. Kennedy Institute for the United States Senate was dedicated by President Barack Obama. The Institute opened to the public on March 31, 2015.

Dorchester is located south of downtown Boston and is surrounded by the neighborhoods of South Boston, Roxbury, Jamaica Plain, Hyde Park and South End, the city of Quincy and the town of Milton. The Neponset River separates Dorchester from Quincy and Milton.

Dorchester is Boston's largest and most populous neighborhood. It comprises many smaller sections and squares. Due to its size of about six square miles (16 km), it is often divided for statistical purposes into North and South Dorchester.

North Dorchester includes the portion north of Quincy, East and Freeport streets. The main business district in this part of Dorchester is Uphams Corner, at the intersection of Dudley Street and Columbia Road.

South Dorchester is bordered to the east by Dorchester Bay and to the south by the Neponset River. The main business districts in this part of Dorchester are Fields Corner, at the intersection of Dorchester Avenue and Adams Street, and Codman Square, at the intersection of Washington Street and Talbot Avenue. Adjacent to Fields Corner is the Harrison Square Historic District, also known as Clam Point. It is notable for its collection of substantial Italianate mansard residences.

Dorchester Avenue is the major neighborhood spine, running in a south–north line through all of Dorchester from Lower Mills to downtown Boston. The southern part of Dorchester is primarily a residential area, with established neighborhoods still defined by parishes, and occupied by families for generations. The northern part of Dorchester is more urban, with a greater amount of apartment housing and industrial parks. South Bay and Newmarket industrial area are major sources of employment.

The Harbor Point area (formerly known as Columbia Point) is home of several large employers, including the Boston campus of the University of Massachusetts, the Massachusetts Archives and Commonwealth Museum, the Edward M. Kennedy Institute for the United States Senate, and the John F. Kennedy Presidential Library and Museum. Distinct commercial districts include Bowdoin/Geneva, Fields Corner, Codman Square, Peabody Square, Adams Village and Lower Mills. Primarily residential areas include Savin Hill, Jones Hill, Four Corners, Franklin Field, Franklin Hill, Ashmont, Meeting House Hill, Neponset, Popes Hill and Port Norfolk.

Up until the 1960s, the Blue Hill Avenue part of Dorchester from Roxbury to Mattapan was primarily composed of Jewish Americans whose ancestors had immigrated from eastern Europe in the late 19th and early 20th centuries. The Neponset neighborhood was primarily Irish-American, most of whom were Catholic.

During the 1920s–1960s, many African Americans moved from the South to the North during the Great Migration and settled on Blue Hill Avenue and nearby sections. While some Jewish-Americans were moving "up and out" to the suburbs, certain Boston banks and real estate companies developed a blockbusting plan for the area. The Blue Hill Avenue area was "redlined" so that only the newly arriving African Americans would receive mortgages for housing in that section. "White flight" was prevalent.

After changes to US immigration law in 1965, Dorchester received new waves of migrants from Puerto Rico, and immigrants from the Caribbean and Central America, such as Dominican Republic, Haiti, Jamaica, and Trinidad and Tobago. Immigrants also came from Cape Verde and Vietnam, as well as other Latin American, Asian, and African nations. Dorchester also continued to receive immigrants from Northern European countries such as Ireland, Germany and Poland. Dorchester became more diverse than at any point in its long history, with many nationalities represented here. These immigrants have helped revive the economy of the neighborhood by opening ethnic stores and restaurants.

The sections of Dorchester have distinct ethnic, racial, and socioeconomic compositions. The eastern areas of Dorchester (especially between Adams Street and Dorchester Bay) are primarily ethnic European and Asian, with a large population of Irish Americans and Vietnamese Americans. Residents of the western, central and parts of the southern sections of the neighborhood are predominantly African American. In Neponset, the southeast corner of the neighborhood, as well as parts of Savin Hill in the north and Cedar Grove in the south, Irish Americans maintain the most visible identity.

In the northern section of Dorchester and southwestern section of South Boston is the Polish Triangle, where recent Polish immigrants are residents. Savin Hill, as well as Fields Corner, have large Vietnamese-American populations. Uphams Corner contains a Cape Verdean-American community, the largest concentration of people of Cape Verdean origin within Boston city limits. Western, central and parts of southern Dorchester have a large Caribbean population (especially people from Haiti, Jamaica, Barbados, and Trinidad and Tobago). They are most strongly represented in the Codman Square, Franklin Field and the Ashmont area, although there are also significant numbers in Four Corners and Fields Corner.

Significant numbers of African Americans live in the Harbor Point, Uphams Corner, Fields Corner, Four Corners and Franklin Field areas. In recent years Dorchester has also seen an influx of young residents, gay men and women, and working artists (in areas such as Lower Mills, Ashmont Hill/Peabody Square, and Savin Hill).

The neighborhood is served by five stations on the Massachusetts Bay Transportation Authority Red Line (MBTA) rapid transit service, five stations on the Ashmont-Mattapan High Speed Line, five stations on the Fairmount Commuter Rail Line, and various bus routes. Over the last decade, the Dorchester branch of the Red Line had major renovations, including four rapid transit stations being rebuilt at Savin Hill, Fields Corner, Shawmut, and Ashmont. At Ashmont station, the city of Boston and the state of Massachusetts partnered with private investors to create The Carruth, one of the state's first Transit-oriented developments (TOD).

Interstate 93 (concurrent with Route 3 and U.S. 1) runs north–south through Dorchester between Quincy, Massachusetts, and downtown Boston, providing access to the eastern edge of Dorchester at Columbia Road, Morrissey Boulevard (northbound only), Neponset Circle (southbound only), and Granite Avenue (with additional southbound on-ramps at Freeport Street and from Morrissey Blvd at Neponset). Several other state routes traverse the neighborhood, e.g., Route 203, Gallivan Boulevard and Morton Street, and Route 28, Blue Hill Avenue (so named because it leads out of the city to the Blue Hills Reservation). The Neponset River separates Dorchester from Quincy and Milton. The "Dorchester Turnpike" (now "Dorchester Avenue") stretches from Fort Point Channel (now in South Boston) to Lower Mills, and once boasted a horse-drawn streetcar.

A number of the earliest streets in Dorchester have changed names several times through the centuries, meaning that some names have come and gone. Leavitt Place, for instance, named for one of Dorchester's earliest settlers, eventually became Brook Court and then Brook Avenue Place. Gallivan Boulevard was once Codman Street and Brookvale Street was once Brook Street. Morrissey Boulevard was once Old Colony Parkway.

Throughout its history, Dorchester has had periods of economic revival and recession. In the 1960s and 1970s, Dorchester was particularly hard hit by economic recession, high unemployment, and white flight.

In 1953, Carney Hospital moved from South Boston to its current location in Dorchester, serving the local communities of Dorchester, Mattapan, Milton and Quincy.

In 1953, a major public housing project was completed on the Columbia Point peninsula of Dorchester. There were 1,502 units in the development on 50 acres (200,000 m) of land. It later became known for high rates of crime and poor living conditions, and it went through particularly bad times in the 1970s and 1980s. By 1988, there were only 350 families living there. In 1984, the City of Boston gave control of it to a private developer, Corcoran-Mullins-Jennison, who redeveloped the property into a residential mixed-income community called Harbor Point Apartments which was opened in 1988 and completed by 1990. It was the first federal housing project to be converted to private, mixed-income housing in the United States. Harbor Point has won much acclaim for this transformation, including awards from the Urban Land Institute, the FIABCI Award for International Excellence, and the Rudy Bruner Award for Urban Excellence.

During the housing crisis of 2008 in the United States, Dorchester's Hendry Street became the epicenter in the media In reaction, the city of Boston negotiated to buy several of the houses for as little as $30,000. It is moving to seize other foreclosed properties on which the owners have not paid taxes. The houses were renovated and added to the inventory of subsidized rental housing.

In 2008, plans and proposals were unveiled and presented to public community hearings by the Corcoran-Jennison Company to redevelop the 30-acre (120,000 m) Bayside Exposition Center site on the Columbia Point peninsula into a mixed use village of storefronts and residences, called "Bayside on the Point". However, in 2009, the Bayside Expo Center property was lost in a foreclosure on Corcoran-Jennison to a Florida-based real estate firm, LNR/CMAT, who bought it. Soon after, the University of Massachusetts Boston bought the property from them to build future campus facilities.

The corporate headquarters of The Boston Globe was also located in Dorchester, having moved there in 1958 from downtown Boston. In 2009, then-owner The New York Times Company put the paper up for bid, leading to concern from local community members, who had seen other major employers close their doors. After negotiations with their union and cost reduction measures, the owner's plans to sell the Globe were abandoned in October 2009. In 2013, the paper was bought by John W. Henry, owner of the Boston Red Sox, and in 2017 the Globe headquarters returned to downtown Boston.

In the 20th century, many of the labor unions in Boston relocated their headquarters to Dorchester. This includes the Boston Teachers Union, International Brotherhood of Electrical Workers Local 103, New England Regional Council of Carpenters, International Association of Fire Fighters Local 718, among others.

Dorchester, with a population of approximately 130,000, is home to nearly one-fifth of all Boston residents. In the early 1990s, Dorchester, along with Roxbury and Mattapan, had the highest percentage of victims with violence-related injuries. Since the early 2000s, crime rates across Boston have declined. In the first three months of 2013, Boston crime rates reportedly dropped 15% compared to the same time period in 2012.

According to the Dorchester Reporter crime maps, the more dangerous areas in Dorchester are west of Columbia Road, with criminal activity centered on the Blue Hill Avenue area. Safer parts of the neighborhood include Savin Hill; the historic neighborhood of Clam Point; Columbia Point, which is populated by mostly UMass Boston students; Ashmont Hill; Saint Mark's; Pope's Hill; Cedar Grove; Lower Mills, around the Neponset, Gallivan, and Morrissey Boulevard areas; and the Jones Hill neighborhood (with the third-largest percentage of same-sex households in Boston after the South End and Jamaica Plain).

According to AreaVibes, Dorchester's overall crime rate is 30% higher than the national average. For every 100,000 people there are 10.55 daily crimes in the neighborhood. Property crime is much more common than violent crime. Out of 100,000 people, 831 are involved in violent crime, and 3,021 out of 100,000 are involved in property crime.

The chance of being a victim of:

• Property crime = 1 in 34
• Violent crime = 1 in 121
• Crime = 1 in 26
