List of Pacific Coast League champions

The Pacific Coast League (PCL) is a Minor League Baseball league that operates in the United States at the Triple-A level, which is one grade below Major League Baseball. A champion has been determined at the end of each season since the league was formed in 1903.

Through 1927, champions were usually the regular-season pennant winners—the team with the best win–loss record at the conclusion of the regular season. From 1928 to 1954, postseason playoffs were the predominant method of determining champions. Participants from 1936 to 1954 were the four teams with the highest winning percentages. After a period of postseason dormancy, the playoffs returned in 1963 along with the advent of a divisional alignment. From 1963 to 1977, the winners of each of two divisions vied for the championship. The league operated using a split season format from 1978 to 1997, with the winners of each half facing off for the right to play for the PCL crown. From 1998 to 2020, the league was split into two conferences of two divisions each. The division winners within each conference met to determine conference champions, and those winners competed for the league championship. The 2021 winner was the team with the best regular-season record. In 2022, the league championship was determined by a single playoff game between the East and West division winners. Beginning with the 2023 season, the league adopted a split season format, in which the league championship is determined by a best-of-three playoff series between the winners of each half of the season, with the winner meeting the champion of the International League in the Triple-A National Championship Game.^[1]

The San Francisco Seals won 14 Pacific Coast League championships, more than any other team, followed by the Los Angeles Angels (12) and the Albuquerque Dukes and Portland Beavers (8). Among active PCL franchises, the Tacoma Rainiers have seven championships, the most of all teams, followed by the Sacramento River Cats (5) and the Oklahoma City Dodgers (3).
