Holy Trinity Church is a historic church building and former parish of the Catholic Church located in the Society Hill neighborhood of Philadelphia, Pennsylvania. Established in 1784, the church was a national parish for Germans and was the first national parish for any ethnicity in the United States. The church merged into a single parish with St. Mary's Church in 2009, and closed in 2019. It is set to be relegated to profane but not sordid use in January 2023.
