Surfside is a town in Miami-Dade County, Florida, United States. Surfside is a primarily residential beachside community, with several multistory condominium buildings adjacent to Surfside Beach on the Atlantic Ocean. The town is bordered on the south by the North Beach neighborhood of Miami Beach, on the north by Bal Harbour, on the west by Biscayne Bay, and on the east by the Atlantic Ocean. It also serves as part of the Miami metropolitan area of South Florida. The population was 5,689 as of the 2020 census.

Between 1923 and 1925, the Tatum Brothers subdivided the land on what is now Surfside.

Starting in 1924, Henri Levy developed Biscaya Island and a portion of land from 87th to 92nd Streets.

In 1929–1930, Russell Pancoast, built the Surf Club 90th Street and Collins Avenue.

In 1935, fearing annexation by the city of Miami Beach, Florida, 35 members of the privately owned club incorporated the Town of Surfside and financed the venture with a $28,500 loan.

Spearman Lewis was the first mayor of Surfside.

In 1956, Surfside purchased the Lehman Estate on the northeast corner of 93rd Street and Collins Avenue. It acquired additional land via eminent domain and then built a community center.

In 1960, Hawthorne Park was dedicated.
