The 1945 Amateur World Series was the eighth edition of the Amateur World Series (AWS), an international men's amateur baseball tournament. The tournament was sanctioned by the International Baseball Federation (which retroactively titled it the 1945 Baseball World Cup). The tournament took place, for the second time, in Venezuela, which had also hosted the previous (1944) tournament. It was contested by six national teams playing ten games each from October 27 through November 18 in Caracas.
The tournament was won by hosts Venezuela, which finished undefeated with a perfect 10–0 record to earn its second consecutive gold medal and third overall. It would be the last major international sporting competition won by the country for 81 years, until Venezuela defeated the United States at the 2026 World Baseball Classic.
