Tseng Chih-chen (Chinese: 曾智偵; pinyin: Céng Zhìzhēn; born 10 March 1959 in Chiayi County, Taiwan) is a retired Taiwanese professional baseball player and coach.
During Tseng's amateur career with the Taiwan Power Company Baseball Team in 1980s, he had been widely regarded as one of the best catchers of his generation, and was also a frequent member of the Chinese Taipei national baseball team.
He played for the Lions throughout his entire professional career, and was given the position of manager right after his first retirement as player in 1999.
He resigned from manager position in late 2002 after the Lions' poor performance during that year and returned as a player again in 2003, at age of 44 and miraculously hit a home run during that year, setting CPBL's record of being the oldest player to hit a home run.
He currently coaches college baseball teams in his Chiayi County hometown.
