Roosevelt (historically known as Greenwich and Rum Point) is a hamlet and census-designated place (CDP) in the Town of Hempstead in Nassau County, on the South Shore of Long Island, in New York, United States.

[2] The community is named for former President Theodore Roosevelt, but was also known as Greenwich and Rum Point for a time before that.

[3][4] While Roosevelt once had a predominantly-white population, white flight and real estate blockbusting became a major issue during the postwar housing boom in the 1950s and 1960s, when the community saw an influx of African-American residents.

12.0% of all households were made up of individuals, and 4.1% had someone living alone who was 65 years of age or older.

[10] However, small portions of the hamlet's southwestern and southeastern corners are located within the boundaries of (and thus served by) the Baldwin Union Free School District and the Freeport Union Free School District, respectively.

[10] Additionally, the portion of the Meadowbrook State Parkway within the hamlet is located within the Merrick UFSD, the North Merrick UFSD, and the Bellmore–Merrick Central High School District.
