The Pacific Coast League Top MLB Prospect Award is an annual award given to the best rookie player in Minor League Baseball's Pacific Coast League based on their regular-season performance as voted on by league managers. Broadcasters, Minor League Baseball executives, and members of the media have previously voted as well. Though the league was established in 1903, the award was not created until 1952 as the Rookie of the Year Award. It was abandoned from 1973 to 1997 before being revived in 1998. After the cancellation of the 2020 season, the league was known as the Triple-A West in 2021 before reverting to the Pacific Coast League name in 2022. The Top MLB Prospect Award began to be issued instead of the Rookie of the Year Award in 2021.
