The Cathedral of Our Lady of the Immaculate Conception (Chinese: 圣母无原罪主教座堂; pinyin: Shèngmǔ wúyuánzuì zhǔjiàojǐtáng) is a Roman Catholic cathedral, located at 415 Zhongshan Road North (中山北路415号) not far from Wulin Square (武林广场) in downtown Hangzhou, China. Since it is the only Catholic church currently in service within the city of Hangzhou itself, it is also known simply as Tiānzhǔ Táng (天主堂) or "the Catholic church".
