The Harlem River Houses is a New York City Housing Authority public housing complex between 151st Street, 153rd Street, Macombs Place, and the Harlem River Drive in the Harlem neighborhood of Manhattan in New York City. The complex, which covers 9 acres (3.6 ha), was built in 1936-37 and opened in October 1937 – one of the first two housing projects in the city funded by the Federal government – with the goal of providing quality housing for working-class African Americans. It has 574 apartments.

The New York City Housing Authority (NYCHA) is a public development corporation which provides public housing in New York City, and is the largest public housing authority in North America. Created in 1934 as the first agency of its kind in the United States, it aims to provide decent, affordable housing for low- and moderate-income New Yorkers throughout the five boroughs of New York City. NYCHA also administers a citywide Section 8 Leased Housing Program in rental apartments. NYCHA developments include single and double family houses, apartment units, singular floors, and shared small building units, and commonly have large income disparities with their respective surrounding neighborhood or community. These developments, particularly those including large-scale apartment buildings, are often referred to in popular culture as "projects."
