The Negro World Series was a post-season baseball tournament which was held from 1924–1927 and from 1942–1948 between the champions of the Negro leagues, matching the mid-western winners against their east coast counterparts. The series was also known as the Colored World Series, especially during the 1920s, and as the Negro League World Series, in more recent books, though contemporary black newspapers usually called it simply, the "World Series", without any modification.
