The Immaculate Conception Cathedral () is a Roman Catholic cathedral in Datong District, Taipei, Taiwan. The Latin Rite church serves as the see of the Metropolitan Archdiocese of Taipei (Archidioecesis Taipehensis; 天主æÂÂèºåÂÂ總æÂÂÃ¥ÂÂ) created by Pope Pius XII with the Bull "Gravia illa Christi".
The original building was built by Spanish in 1629, but was destroyed in a raid. Between 1911 and 1914, a new church was built in the Gothic style. Towards the end of World War II, the church was one of many buildings damaged by the air raid. Reconstruction began in 1959 of the church, albeit much simpler than the original, and was completed in May 1961.
All Masses and other religious services in the cathedral are offered in Mandarin Chinese.
The church is accessible within walking distance west of Shuanglian Station of the Taipei Metro.
