Immaculate Conception Parish Church, commonly known as Guiuan Church, is a Roman Catholic church in the municipality of Guiuan, Eastern Samar, Philippines, within the jurisdiction of the Diocese of Borongan.
The church is classified as a National Cultural Treasure by the National Museum of the Philippines. It was formerly nominated to the UNESCO World Heritage Sites of the Philippines under two categories, the Baroque Churches of the Philippines (Extension) and the Jesuit Churches of the Philippines.
The church, built in the 18th century, was significantly damaged when Typhoon Haiyan (local name: Yolanda) made landfall in Guiuan and struck other parts of Central Visayas on November 8, 2013. While the church's roof was destroyed and the façade damaged, the church's walls were largely left intact. Restoration of the damaged church was completed in 2019.
