The Assumption of Our Lady Parish Church, commonly known as Tanauan Church, is a Roman Catholic church located in Tanauan, Leyte, Philippines. It is under the jurisdiction of the Archdiocese of Palo. First built in 1704, the church was later expanded in 1860 by adding a transept and surrounding it with a wall and watchtowers for defense against pirates. It survived the tidal wave that hit Tanauan in 1897.

The National Historical Commission of the Philippines (NHCP) declared the church a national historical landmark in 1949.

During Typhoon Haiyan in 2013, the church served as an evacuation center for the locals.
