Irvington is a township in Essex County, in the U.S. state of New Jersey. As of the 2020 United States census, the township's population was 61,176, an increase of 7,250 (+13.4%) from the 2010 census count of 53,926, which in turn reflected a decline of 6,769 (−11.2%) from the 60,695 counted in the 2000 census.

The township had the ninth-highest property tax rate in New Jersey in 2020, with an equalized rate of 4.890% in 2020, compared to 2.824% in the county as a whole and a statewide average of 2.279%.

Clinton Township, which included what is now Irvington, Maplewood and parts of Newark and South Orange, was created on April 14, 1834. The area was known as Camptown until the mid-1800s. In 1850, after Stephen Foster published his ballad, Camptown Races, residents were concerned that the activities described in the song would be associated with their community. The town was renamed, Irvingtown, in honor of Washington Irving.

Irvington was incorporated as an independent village on March 27, 1874, from portions of Clinton Township. What remained of Clinton Township was absorbed into Newark on March 5, 1902. On March 2, 1898, Irvington was incorporated as a Town, replacing Irvington Village. In 1982, the town was one of four Essex County municipalities to pass a referendum to become a township, joining 11 municipalities that had already made the change, of what would ultimately be more than a dozen Essex County municipalities to reclassify themselves as townships in order take advantage of federal revenue sharing policies that allocated townships a greater share of government aid to municipalities on a per capita basis.

From 1887 to 1965, Irvington was home to Olympic Park, a 40-acre (16 ha) amusement park that straddled the border of Irvington and Maplewood, with the main entrance on Chancellor Avenue and a side entrance on 40th Street. After the park closed, the merry-go-round was sold and transported to Disney World, in Orlando, FL. The book, Smile: A Picture History of Olympic Park, 1887–1965 written by Alan A. Siegel was published in 1983 by Rutgers University Press.

The 1967 Newark riots hastened an exodus of families from that city, many of them moving a few short blocks into neighboring Irvington. Until 1965, Irvington was almost exclusively white. By 1980, the town was nearly 40% black; by 1990 it was 70%.

On July 1, 1980, Fred Bost, was sworn in as East Ward Councilman, making him the first black person to serve on the Town Council. At age 24, Michael G. Steele became the first black elected to public office in Irvington when he won a seat on the school board on March 25, 1980, then became the township's first black mayor ten years later, when he was elected in 1990 and served for four years, followed by Sarah Brockington Bost in 1994. In 1994 Steele returned to the Board of Education to pursue his career as the district's certified School Business Administrator, serving over 22 years. The current mayor is Tony Vauss.

According to the United States Census Bureau, the township had a total area of 2.92 square miles (7.55 km), including 2.91 square miles (7.55 km) of land and <0.01 square miles (0.01 km) of water (0.07%).

The Elizabeth River runs through the city passing Civic Square and Clinton Cemetery. Unincorporated communities, localities and place names located partially or completely within the township include Irving Place.

The township is bordered by Maplewood to the west and Newark to the east, both in Essex County, and Hillside to the south and Union to the southwest, both in Union County, New Jersey.

In 2007, the New Jersey State Police reported that Irvington had a violent crime rate of 22.4 incidents per 1,000 population, the highest of all 15 major urban areas in the state.

In July 2015, the central business district surrounding the Irvington Bus Terminal on Springfield Avenue was designated as one of 33 transit villages statewide, qualifying it for incentives for revitalization.

Irvington had six movie theatres that provided live stage appearances or films for their patrons amusement. The theatres were built in the 1920s during the era of silent films. A few theaters were installed with Wurlitzers, such as the Castle, Chancellor, and Sanford. A Wurlitzer opus 1885 was installed at Chancellor Theater, known prior as the Roxy or Rex. The Sanford had a Wurlitzer organ opus 1301 installed. The organs were used for silent movies, stage acts, or intermissions. Motion pictures began to increase in showings during the 1940s and 1950s, but downturn in audience turn-out resulted in theaters to close during the 1970s. As of 2024, there are no movie theaters operating in the township.

Irvington is governed within the Faulkner Act, formally known as the Optional Municipal Charter Law, under the Mayor-Council form of municipal government, one of 71 municipalities (of the 564) statewide that use this form. The governing body is comprised of the Mayor and the seven-member Township Council, whose members are elected to staggered four-year terms of office on a non-partisan basis in municipal elections held on the second Tuesday in May in even-numbered years. The mayor and the three at-large seats are elected together and two years later the four ward seats are up for vote together. The council selects a president, first vice president and second vice president from among its members at a reorganization meeting held after each election. The council is the legislative body of the township and needs a ⅔ majority to make changes to the budget submitted by the mayor. The mayor is the township's chief executive and is responsible for overseeing the day-to-day operations and submitting a budget, but is not eligible to vote on the council and is not required to attend its meetings.

As of July 2022, the mayor of Irvington is Tony Vauss, whose term of office ends June 30, 2026. Members of the Township Council are Council President Renee C. Burgess (At-large, 2026), Council First Vice President Octavio Hudley (At-large, 2026), Council Second Vice President Charnette Frederic (At-large, 2026), Jamillah Z. Beasley (South Ward, 2024), Vernal C. Cox Sr. (West Ward, 2024), Sean C. Evans (East Ward, 2024) and Orlander Glen Vick (North Ward, 2024).

In April 2019, Jamillah Z. Beasley was appointed to fill the South Ward seat expiring in December 2020 that became vacant following the death of Sandra M. Jones. He served on an interim basis until the November 2019 general election, when he was elected to serve the balance of the term of office.

Council President David Lyons, who had served six terms in office representing the North Ward, died in August 2019.

Both Mayor Vauss and Municipal Clerk Harold Wiener denied filing the lawsuit when interviewed, with Wiener commenting "She does file a lot of OPRAs. That comes with the territory, my territory. I know Ms. McDaniel. I don’t have a problem with her." After being the first to report on the story, WNBC was sent two cease and desist letters by the township, accusing them of harassment as well. After the lawsuit became widely publicized, Irvington dropped it.
