Chinese Professional Baseball League

The Chinese Professional Baseball League (CPBL; Chinese: 中華職業棒球大聯盟; pinyin: Zhōnghuá Zhíyè Bàngqiú Dàliánméng) is the top-tier professional baseball league in Taiwan. The league was established in 1989 and played the first season in 1990. CPBL eventually absorbed the competing Taiwan Major League in 2003. As of the 2025 season, the CPBL consists of six organizations, all of which have teams in the main league and farm league.

The CPBL consists of Major (Chinese: 一軍; lit. 'first/primary corps') and, since 2006, Minor (Chinese: 二軍; lit. 'second/reserve corps') leagues, with the Minor league team rosters consist of developmental and injury-recovering players. In comparison to Minor League Baseball, the CPBL is considered to be at a Single-A level, with a wider spread of talent and more offense than American leagues.

CPBL TV is CPBL's official paid live-streaming and video-on-demand platform. It receives signals from each team's broadcasting partners and is available worldwide.

Baseball was first introduced to Taiwan during Japanese rule, and gained popularity when the national little league baseball teams won numerous Little League World Series championships in the 1970s and 1980s. The national baseball team also performed exceptionally well in many international competitions. However, the development of baseball in Taiwan was limited due to the lack of a professional league, and therefore many players were reluctant to commit to the sport.

The idea of forming a professional baseball league in Taiwan was first suggested by local Brother Hotel's chairman Hung Teng-sheng (洪騰勝). He formed his amateur Brother Hotel baseball team in 1984, and intended to professionalize his team and form a professional league within a few years. Throughout 1988 and 1989, Hung visited numerous Taiwanese businesses, trying to convince them to form professional baseball clubs. Most of his requests were rejected, but Wei Chuan Corporation, Mercuries Chain Stores, and Uni-President Corporation all supported the idea and formed teams. The Chinese Professional Baseball League was established on October 23, 1989, with Hung Teng-sheng acting as secretary-general. Because of his contribution to professional baseball in Taiwan, Hung is sometimes referred to as the "Father of the CPBL." Chung Meng-shun (鍾孟舜) designed every original logo of the four founding teams.

With the popularity rise in the first few years, the Jungo Bears and China Times Eagles joined in 1993. The Koos Group Whales joined in 1997. The league consisted of seven teams in the 1997 season which is the maximum in CPBL history.

The Black Eagles Incident in 1997 resulted in a major popularity decline. The China Times Eagles became defunct after the 1997 season. The Wei Chuan Dragons and Mercuries Tigers also became defunct after the 1999 season, prior to which the Dragons had won all championships from 1997 to 1999.

In 1997, the newly founded Taiwan Major League began to compete with the CPBL. The two leagues were often competing with each other, but eventually, the TML merged with the CPBL.
