Chinese Professional Baseball (CPB; ) is the top-tier professional baseball league in China. The league was formed in 2025 and began play on January 1, 2026, co-existing with the state-run China Baseball League as the main professional league in the nation. It is organized by Shanghai-based CoolBang Sports.
The formation of the league was announced on September 28, 2025. The CPB's first draft was held on November 26, 2025, during which the five founding teams selected 57 players from Greater China and overseas. Prominent Taiwanese and international baseball figures were announced to have joined the league, including Lu Wen-sheng, Dae-sung Koo, and Ray Chang, who were selected as managers for the Fuzhou Sea Knights, Shanghai Dragons, and Shenzhen Bluesox respectively.
The inaugural CPB season opened with the first game of the Spring League () on January 1, 2026. Four founding teams played a total of 30 regular-season games during the Spring League followed by a best-of-three championship series. A 12-week Summer League () will be held in July, during which Changsha Want Want Happy will begin play. Games are primarily played at Zhongshan Baseball Park in Shenzhen, with some games played at the Zhongshan International Baseball and Softball Center ("Baseball City") in Zhongshan.
According to the World Baseball Softball Confederation, the 2027 CPB season will largely follow the format of the 2026 season. The league is anticipated to move to a home-and-away schedule for the 2028 season and will retain the Spring League as a preseason spring training series, by which point the league hopes to have achieved "fully professional" state following more investment in player development.
The league assembled the eight-member CPB Girls cheerleading squad, consisting of famous cheerleaders from Taiwan and others selected from a draft in December 2025. The squad was later expanded to twelve members.
The league debuted a theme song titled "Arrogance", written by Taiwanese singer-songwriter , during a live performance at a Spring League championship series game on January 30, 2026. In addition, each team also has its own fight song.
