The Negro leagues were United States professional baseball leagues comprising teams predominantly made up of African Americans and, to a lesser extent, Latin Americans. The term may be used broadly to include professional black teams outside the leagues and it may be used narrowly for the seven relatively successful leagues beginning in 1920 that are sometimes termed "Negro Major Leagues."

The first known baseball game between two black teams was held on November 15, 1859, in New York City. The Henson Base Ball Club of Jamaica, Queens, defeated the Unknowns of Weeksville, Brooklyn, 54 to 43.

By the end of the 1860s, the black baseball mecca was Philadelphia, which had an African-American
