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, in part due to the effects of World War II. The United States withdrew part-way and forfeited their last four games; it would be the last Amateur World Series contested by the U.S. until the 1969 Amateur World Series.
