St. John's Cathedral (Chinese: 聖約翰座堂) is a Christian church, located at No. 280, Second Section, Fuhsing South Road, Taipei, Taiwan. It is the diocesan Cathedral of the Episcopal Diocese of Taiwan (Chinese: 臺灣聖公會, 聖公會臺灣教區).
A large building structure in southern Taipei, familiar to many Taipei-ites, St. John's Cathedral was built in 1955 by the Chinese Anglican-Episcopalians who had left mainland China in 1949. It became the diocesan cathedral of the Diocese of Taiwan in 1961-1962 as this diocese was officially established. The annex building was later added, in 1963. .
