The 1948 Negro World Series was the championship tournament for the 1948 season of Negro league baseball. It was the seventh edition of the second incarnation of the Negro World Series and the eleventh overall played. It was a best-of-seven playoff played between the Homestead Grays of the Negro National League and the Birmingham Black Barons, champions of the Negro American League. The Homestead Grays played home games in both Washington, D.C. and Pittsburgh. It was the fifth appearance for the Grays in the Series, the most for any team; Birmingham made their third appearance in the Series, with each being against the Grays (losing in 1943 and 1944). The Grays would win the series in five games. The Black Barons featured the 17-year-old Willie Mays in his first professional season.
