The 1939 Amateur World Series was the second 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). Great Britain did not defend the AWS title it had won in the inaugural event the previous year. The tournament took place, for the first time, in Cuba. It was contested by the national teams of Cuba, Nicaragua and the United States, playing six games each from August 12 through August 26. Cuba won its first AWS title – the first of what would be a record 26 titles by the time the series ended in 2011, 22 more titles than the next closest nation.
