Algiers (/ælˈdʒɪərz/) is a historic neighborhood of New Orleans and is the only Orleans Parish community located on the West Bank of the Mississippi River. Algiers is known as the 15th Ward, one of the 17 Wards of New Orleans. It was once home to many jazz musicians and is also the second oldest neighborhood in the city.

Algiers was established in 1719 as a plantation, not a neighborhood. Originally called the "King's Plantation," it was first used as the location for the city's powder magazine, a holding area for the newly arrived enslaved Africans. Decades later, it became a port call for the displaced Cajuns.

Developed as a town by Barthelemy Duverjé, Algiers expanded due mainly to the shipbuilding and repair industries of the dry docks and the extensive railroad yards. A large part of the town surrounding the Courthouse was destroyed by fire in 1895 but rose again like a Phoenix from the ashes.

In 1870, Algiers was annexed to the city as the 15th Ward, an arrangement which has remained despite repeated discussions of secession. Until the latter 1930s, rail yards housed large amounts of freight and rolling stock, which was brought back and forth across the Mississippi River by barge. Then, the Huey P. Long Bridge, which included a railway bridge, was built upriver at Bridge City, Louisiana. The largest railroad presence had been the Southern Pacific yard. That location is still known to Algerines as "the SP yard." For decades, it was largely a vacant strip. Portions of the tract were redeveloped for housing in the early 21st century. In the yard's active days, a steam-powered Southern Pacific train ferry brought railroad cars from there across the Mississippi River.

In 1901, the U.S. Navy established a naval station in Algiers. During the early 20th century, Algiers was segregated due to the Jim Crow Laws of the Southern United States. Under Jim Crow, blacks were not allowed to live in Algiers Point, which was tended for whites or Creoles of color who passed as white. Blacks occupied the area downriver from Algiers Point called McDonoghville (locals refer to it as "Over the Hump"). The neighborhood was named after John McDonogh. Before his death in 1850, McDonogh established "Freetown" for formerly enslaved people and other people of color. Freetown was renamed McDonoghville in 1815. When Algiers became a part of Orleans Parrish in 1870, it became the largest populated black community on the West bank of the Mississippi River. Many Jazz artists such as Kid Thomas Valentine, Red Allen, and Papa Celestin all grew up in McDonoghville section in Algiers during the 1910s. Some of the early black neighborhoods included Riverview, Tunisbourg McCLendonville, LeBeoufville, Hendeeville, Oakdale, and Whitney. In 1938, L.B. Landry High School opened as the first all-black school in Algiers. The school was named after Dr. Lord Beaconsfield Landry, who lived in the area and died in 1934. It was also one of the first schools in New Orleans to serve African Americans.

Around the 1930s and early 1940s, several other schools and neighborhoods were built for blacks, including Peter S. Lawton School and Oakdale. Oakdale once stood on the edge of Jefferson Parish and stretched from Whitney Avenue to the Mississippi River. It was destroyed in the late 1950s to make room for the Greater New Orleans Bridge.

Newton Street became the heart of Algiers's black community as it was once filled with ballrooms, saloons, and Juke joints. Popular hangout spots like Kohlman's Tavern, Ping Pong Club, and Whitney's Ballroom attracted hundreds of people every weekend. The most famous, Greystone Voter's League, became the place for Rhythm & Blues shows and great singers such as Ray Charles, Son House, and B. B. King, who all played there. Most of the jazz venues in Algiers closed by the 1970s.

Algiers slowly declined after suburban neighborhoods were developed and expanded along Gen. Meyer and Gen. De Gaulle. Many white families from the older parts of the city began moving into the newly built sections of Algiers. Behrman Heights, initially built to house military families regardless of race, became the first racially integrated community. Aurora and Walnut Bend subdivisions remained white. The oil industry provided many jobs and sustained the growth of commerce. In 1970, New Orleans Public Schools opened a second high school, O. Perry Walker. O. Perry Walker was named after former New Orleans Public Schools superintendent Oliver Perry Walker, who supported segregation. During the early 1970s, Whites had begun to move out of Behrman Heights after the Housing Authority of New Orleans opened the Christopher Park Homes for low-income black families. The building of public housing led to White flight. The White flight resulted in a major decline as many businesses left Algiers for more sustainable neighborhoods in the neighboring Jefferson Parish.

Algiers was home to various jazz pioneers such as Red Allen, Peter Bocage, George Lewis, Papa Celestin, Kid Thomas Valentine and many others. Jazz musicians of the 1920s referred to Algiers as the "Brooklyn of the South", the latter for its proximity to New Orleans as compared to New York and Brooklyn, both separated by a river. Algiers also has a long history of Brass bands. The most notable is the Algiers Brass Band, one of the oldest traditional brass bands still active in the city. There were several social halls, including Algiers Masonic Hall, the Elks Hall, and the Ladies of Hope Benevolent Hall, where early jazz was played. There is some jazz parading in the neighborhood today.

Algiers has many nicknames such as A.L.G. and 1.5 but most commonly refer to as the Westside of New Orleans or simply "Westside" by locals.

Algiers is predominantly African American, with 89.4% of residents identifying as such in the 2000 Census.

Algiers lies within NOPD's 4th District jurisdiction of Orleans Parish. The 4th District violent crime rate in low-income neighborhoods has been high since the late 1980s. These areas include the notorious Fischer Projects, Whitney, and Behrman Heights neighborhoods.

Between 1987 and 1988, 4th District's violent crime rate doubled with the biggest increase in gun homicides. Algiers made national headlines during 1981 with the "Algiers 7" case in which seven officers were indicted for killing and torturing black families in revenge for the slaying of NOPD officer Gregory Newport in 1980. Throughout the 1990s, homicides were the only violent crime that remained high in the district, reaching 29 in 1995 which was a slight decrease from 1991.

In 2015, the district tallied 25 homicides, 26 in 2021. In 2022, the district was second in homicides behind Eastern New Orleans, with 38 homicides.

In 2017, 4th district teamed with the NOPD's street-gang unit to quell gun battles spurred by conflicts between neighborhood groups. The groups were formed of loose associations among people, not stable enough to be considered traditional gangs, and had "some very petty, petty beefs that led to very violent encounters," he said. To reduce crime, law enforcement installed 13 crime surveillance cameras, including ten fixed cameras and three mobile cameras, along with five license-plate readers, including three fixed readers and two mobile readers.
