Robert Taylor Homes was a public housing project in the Bronzeville neighborhood on the South Side of Chicago, Illinois from 1962 to 2007. The second largest housing project in the United States, it consisted of 28 virtually identical high-rises, set out in a linear plan for two miles, with the high-rises regularly configured in a horseshoe shape of three in each block. It was located along State Street between Pershing Road and 54th Street, east of the Dan Ryan Expressway. The project was named for Robert Rochon Taylor (1899–1957), an African-American activist and the first African American chairman of the Chicago Housing Authority (CHA). It was a part of the State Street Corridor which included other CHA housing projects: Stateway Gardens, Dearborn Homes, Harold Ickes Homes, and Hilliard Homes.
