The United American Cemetery is the oldest African-American cemetery in Ohio, located on Duck Creek Road in Cincinnati, Ohio and founded in 1844 by the United Colored American Association.

[1] Among those interred at the cemetery who are notable are Horace Sudduth, an early twentiethcentury real estate speculator and owner of the Manse Hotel in Walnut Hills, and John Isom Gaines, a black educator.

The entrance is on the north side of Duck Creek Road, about 1500 feet east of Kennedy Avenue.

By the middle of the twentieth century the cemetery became increasingly neglected.

The courts appointed a new board to operate the cemetery but the board was unable to convince plot owners to pay for perpetual care which would generate funds for ongoing cemetery maintenance.
