The 1942 Amateur World Series was the fifth edition of the Amateur World Series (AWS), an international men's amateur baseball tournament. The tournament was sanctioned by the International Baseball Federation (which titled it the Baseball World Cup as of the 1988 tournament). The tournament took place, for the fourth consecutive time, in Cuba. It was contested by four national teams playing twelve games each from September 26 through October 20 in Havana. Cuba won its third AWS title.
There was a noticeably lower participation of teams as the effects of World War II started to be felt in the Pacific. The United States withdrew and forfeited their last four games. Therefore, the number of games contested, as opposed to slated, was actually 26.
