The 1927 Colored World Series was the championship tournament for the 1927 season of Negro league baseball. It was the fourth overall Series played. It matched the Chicago American Giants, champions of the Negro National League (1920–1931) and the Bacharach Giants of Atlantic City, New Jersey, champions of the Eastern Colored League. The Giants won the series five games to three (with one tie). The two teams had faced a year earlier in the 1926 Colored World Series with the same result.
