The United Presbyterian Church of North America (UPCNA) was an American Presbyterian denomination that existed for one hundred years. It was formed on May 26, 1858 by the union of the Northern branch of the Associate Reformed Presbyterian Church (Covenanter and Seceder) with the Associate Presbyterian Church (Seceders) at a convention at the Old City Hall in Pittsburgh. On May 28, 1958, it merged with the Presbyterian Church in the United States of America (PCUSA) at a conference in Pittsburgh to form the United Presbyterian Church in the United States of America (UPCUSA).
