The First Unitarian Church in Baltimore, Maryland was the first building erected for Unitarians in the United States. Dedicated on 29 October 1818, the church is a domed cube with a stucco exterior. The church, originally called the "First Independent Church of Baltimore", is the oldest building continuously used by a Unitarian congregation. The name was changed in 1935 to "The First Unitarian Church of Baltimore (Unitarian and Univeralist)" following the merger with the former Second Universalist Church at East Lanvale Street and Guilford Avenue in East Baltimore. The Unitarians (founded 1825) and Universalists merged as a national denomination in 1961.
