The 2021 Chinese Professional Baseball League season was the 32nd season of the Chinese Professional Baseball League, with an official slogan of "United for Baseball".
The re-activated Wei Chuan Dragons rejoined the major league 21 years after disbandment in 1999, marking the first time a CPBL season included more than four teams since the 2008 season. As CPBL Commissioner Wu Chih-yang termed out following the conclusion of the 2020 season, the general managers elected Vice President of the Legislative Yuan Tsai Chi-Chang as the new Commissioner.
The season started on March 13, with the opening game played, per tradition, by the prior season's championship series pair: the 2020 champion Uni-President Lions defeated CTBC Brothers at Tainan Municipal Baseball Stadium, 10–4. The season ended in late November, followed by a Taiwan Series rematch. The Brothers defeated the Lions in a four-game sweep to capture the 2021 championship.
