The Taiwan Series (Chinese: 台灣大賽) is the final championship series of the Chinese Professional Baseball League (CPBL). It is usually played in late October or early November, after the regular season. It was formerly known as the CPBL Seasonal Championship Series (Chinese: 中華職棒年度總冠軍賽), and was renamed the Taiwan Series after the merger of the CPBL and the Taiwan Major League in 2003.
