Gaines High School

Gaines High School was a high school for African Americans and also later served as a normal school training teachers in Cincinnati, Ohio. It opened in 1866 and was named for school board member John I. Gaines, an advocate of schools for African Americans in Ohio. It was one of Ohio's first public high schools for African Americans. Peter H. Clark and then William H. Parham served as its principals. The year of the school's closure is uncertain; sources say 1887 or 1890. A historical marker commemorates the school.

Clark introduced baseball as part of the school's program.

Clark became a Socialist and joined the Democratic Party, costing him support in the African American community and his job.

Privately funded Gilmore High School, also known as Cincinnati High School or Cincinnati High School for Colored People, preceded it.
