Longwood is a mixed-use neighborhood in the southeast Bronx in New York City. Its boundaries, starting from the north and moving clockwise are East 167th Street to the north, the Bronx River and the Bruckner Expressway to east, East 149th Street to the south, and Saint Anns Avenue to the west. Southern Boulevard is the primary thoroughfare through Longwood.

The neighborhood is part of Bronx Community District 2, and its ZIP Codes include 10455 and 10459. The neighborhood is served by the New York City Police Department's 41st Precinct. NYCHA property in the area is patrolled by P.S.A. 7 at 737 Melrose Avenue in the Melrose section of the Bronx. The local subway, the 6 and <6>​ trains, operates along Southern Boulevard.

The Bronx initially began to urbanize with the construction of a streetcar network. Eventually, the expansion of the elevated and subterranean rapid transit lines from Manhattan rapidly accelerated development. Solid rows of 5 and 6 story, walk-up and larger elevator, apartment buildings were built to the sidewalk and dominated the landscape of Upper Manhattan, the West Bronx and in walking proximity of the elevated lines in the East Bronx. Commercial corridors quickly developed in close proximity to rapid transit stations and primary thoroughfares. Early in this construction boom, Longwood was one of the most dense and developed Bronx neighborhoods. For much of the first half of the 20th century, the Bronx was overall home to a predominantly middle-class population of European and Jewish descent hailing from diverse nationalities, including immigrants directly from the corresponding countries of varying socioeconomic statuses.

Beginning in the 1950s, the older, more developed parts of the Bronx experienced a socioeconomic shift due to a number of factors. The construction of the Cross Bronx Expressway displaced thousands and physically divided communities, Co-op City in the northeast Bronx offered modern amenities and spacious apartments, and suburban communities outside New York City became more appealing with their auto-centric lifestyle. As people with financial means began to leave, impoverished people often replaced them. White flight and abandonment only accelerated over time. By the late 1970s, many buildings in the greater South Bronx had been burnt out in an epidemic wave of arson. Scammers realized they could manipulate the system and collect insurance money after more lucrative tenants had fled. The area was severely run down as the community became increasingly disfranchised. At this time, crime reached such a level that the 41st Precinct building at 1086 Simpson Street became known by the police as "Fort Apache".

The wave of arson eventually ended with the help of community groups such as Banana Kelly CIA, Inc. and SEBCO (South East Bronx Community Organization), who worked to bring recognition and protect the remaining apartment buildings in the greater South Bronx. What was left was a wasteland of abandoned buildings, vacant lots, filthy streets and a severe lack of even basic commercial amenities. During this period of time, the neighborhood was dealt another blow as violent crime hit historic highs during the crack epidemic. The police seemed to be fighting a losing battle as many young men in New York City were killed on the streets over drug turf. The greater South Bronx was one of the hardest hit areas, with a largely poor population which lacked local jobs, many began to turn to the lucrative drug trade.

Some of the first federal funding in decades for new investment began in 1986 under the Ed Koch administration. In blighted neighborhoods across the city, various housing experiments were attempted. The NYCHA was one of the first agencies to create and renovate residential units in Longwood, the city soon followed up with independent, locally driven developments. This construction resulted in escalating reinvestment in these communities Continuing into the mid-1990s, local and federal governments invested over $550 million in new subsidized residential housing and the expansion of businesses and commerce. This period saw the construction of the South Bronx headquarters of the Police Athletic League of New York City and the relocation of the 41st Precinct of the NYPD from Simpson Street to Longwood Avenue. In addition, investments were made to the Banana Kelly High School, and to several small and large businesses. This investment has only increased exponentially since that time. A vast number of new housing and commercial units have been constructed on formally vacant lots, with more planned. A community once dominated by blight and disinvestment, is now towered over by modern apartment buildings, renovated pre-war structures, and rows of attached row houses. Social problems persist due to a significant percentage of the population living in poverty. Crime, for instance, has declined versus historic highs in the 1990s, but remains significantly above average for New York City. Nonetheless, the neighborhood remains a symbol of social and economic improvement.

The neighborhood predominantly consists of Latin Americans (Longwood has one of the highest concentrations of Puerto Ricans in New York City) but includes a small yet diverse mix of races, ethnic groups, religious affiliations, sexual orientations, and national origins. Like most neighborhoods in New York City, the vast majority of households are renter occupied. Almost half of the population lives below the federal poverty line and receives public assistance (AFDC, Home Relief, Supplemental Security Income, and Medicaid). This community was once part of New York's 16th congressional district, the poorest such district in the United States. After redistricting, it is now part of New York's 15th congressional district and no longer the poorest district in the United States. There is significant income diversity on a block by block basis.

Based on data from the 2010 United States Census, the population of Longwood was 26,196, an increase of 3,114 (13.5%) from the 23,082 counted in 2000. Covering an area of 246.55 acres (99.78 ha), the neighborhood had a population density of 106.3 inhabitants per acre (68,000/sq mi; 26,300/km).

The racial makeup of the neighborhood was 1.5% (382) White, 22.4% (5,866) African American, 0.1% (32) Native American, 0.5% (135) Asian, 0.0% (9) Pacific Islander, 0.3% (78) from other races, and 0.6% (163) from two or more races. Hispanic or Latino of any race were 74.6% (19,531) of the population.

The entirety of Community District 2, which comprises Longwood and Hunts Point, had 56,144 inhabitants as of NYC Health's 2018 Community Health Profile, with an average life expectancy of 78.9 years. This is lower than the median life expectancy of 81.2 for all New York City neighborhoods. Most inhabitants are youth and middle-aged adults: 28% are between the ages of between 0–17, 29% between 25–44, and 21% between 45–64. The ratio of college-aged and elderly residents was lower, at 12% and 10% respectively.

As of 2017, the median household income in Community Districts 1 and 2, including Melrose and Mott Haven, was $20,966. In 2018, an estimated 29% of Longwood and Hunts Point residents lived in poverty, compared to 25% in all of the Bronx and 20% in all of New York City. One in eight residents (12%) were unemployed, compared to 13% in the Bronx and 9% in New York City. Rent burden, or the percentage of residents who have difficulty paying their rent, is 58% in Longwood and Hunts Point, compared to the boroughwide and citywide rates of 58% and 51% respectively. Based on this calculation, as of 2018, Longwood and Hunts Point are gentrifying.

Longwood is dominated by pre-war, 5- and 6-story apartment buildings. Starting in the 1990s, a construction boom has resulted in a number of modern apartment buildings and row houses. Much of the original housing stock was structurally damaged by arson and eventually razed by the city between mid and late 1980s.

The total land area is roughly 0.5 square miles (1.3 km). The terrain is somewhat hilly.

Southern Boulevard is a long-standing, mixed-use district. The Southern Boulevard Business Improvement District, formed in 2008, sits between the two points of closest proximity for the IRT Pelham and White Plains Road Lines. Other primary thoroughfares contain amenities like supermarkets, pharmacies, barbershops, hair salons, fast food, bodegas, and cheap shops.

The Crossings is a two-level 40,000-square-foot (3,700 m) mall at the intersection of Hunts Point Avenue and Bruckner Boulevard. Initially, the project included a residential component, but was quickly scrapped, much to the dismay of the community.

The landmarked Longwood Historic District is located south of Longwood Avenue along Beck, Kelly, Dawson Streets and Hewitt Place. The district largely consists of semi-detached row houses, most of which were designed by one architect, Warren C. Dickerson.
