Linwood is a city in Atlantic County, New Jersey, United States. As of the 2010 United States Census, the city's population was 7,092, reflecting a decline of 80 (-1.1%) from the 7,172 counted in the 2000 Census, which had in turn increased by 306 (+4.5%) from the 6,866 counted in the 1990 Census.
Linwood was originally incorporated as a borough by an act of the New Jersey Legislature on February 20, 1889, from portions of Egg Harbor Township, based on the results of a referendum held the previous day. Linwood was reincorporated as a city on April 27, 1931. The area had been called Leedsville until 1880, when a post office was being established. The United States Postal Service insisted that the name had to be changed as it conflicted with an existing post office elsewhere in the state. Among the names proposed and considered by local residents were "Brinola", "Geneva", "Pearville" and "Viola", with "Linwood" ultimately chosen.
According to the United States Census Bureau, the city had a total area of 4.21 square miles (10.91 km2), including 3.81 square miles (9.87 km2) of land and 0.40 square miles (1.04 km2) of water (9.55%).
The city is located about 9 miles (14 km) west of Atlantic City. It borders the municipalities of Egg Harbor Township, Northfield and Somers Point. Linwood is known for its large, expensive homes, particularly in communities such as The Gold Coast, Fischer Woods, and Fischer Greene.
