Ulysses Franklin Grant was an American baseball player in the 19th century. Early in his career, he was a star player in the International League, shortly before race-based restrictions were imposed that banned African-American players from organized baseball. Grant then became a pioneer in the early Negro leagues, starring for several of the top African-American teams of the late 19th and early 20th centuries. He is widely considered to have been the greatest African-American player of the 19th century. In 2006, Grant was elected to the National Baseball Hall of Fame.

The Negro leagues were United States professional baseball leagues comprising teams of African 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".
