The Ethiopian Art Theatre — originally called the Chicago Folk Theatre, later the Colored Folk Theatre, also referred to as The Ethiopian Art Players — was an African American theatre company based out of Chicago, Illinois.
 The company was an influential albeit short-lived (1922/1923–1925) group founded during the Harlem Renaissance.
 There are differing views over the precise year that the company was founded, 1922 or 1923.
 The founder was Raymond O'Neil, a white theatre director, and its principal sponsor was Mrs. Sherwood Anderson, also white; though all its performers were African American.
 The organization was unique and controversial during its era, primarily for being one of the few African American Theatre Companies to perform European theatrical works, but also, among other things, for producing theatrical works of African American playwrights for both African American and Non-African American audiences.
