St Joseph's Church (Khmer: ព្រះវិហារសន្តយ៉ូសែប, French: Église Saint-Joseph) is a prominent Roman Catholic church in Phnom Penh, Cambodia. Originally a Catholic seminary converted into a temporary place of worship following the destruction of Catholic churches by the Khmer Rouge in the 1970s, it served as the city's main Catholic parish until the completion of a new pro-cathedral in February 2025. The modern St Joseph's Church blends traditional Khmer architectural elements with Latin ecclesiastical design, marking a significant milestone in the revival of Catholicism in Cambodia. Located approximately three kilometers north of Phnom Penh's city center near the Tonle Sap River along National Highway 5 (N5), it remains a spiritual hub for the local Catholic community, which includes a substantial population of Vietnamese descent.
