The American Unitarian Association (AUA) was a religious denomination in the United States and Canada, formed by associated Unitarian congregations in 1825. In 1961, it consolidated with the Universalist Church of America to form the Unitarian Universalist Association.[1]

The AUA was formed in 1825 in the aftermath of a split within New England's Congregational churches between those congregations that embraced Unitarian doctrines and those that maintained Calvinist theology.[2]

According to Mortimer Rowe, the Secretary (i.e. chief executive) of the British Unitarians for 20 years, the AUA was founded on the same day as the British and Foreign Unitarian Association: "By a happy coincidence, in those days of slow posts, no transatlantic telegraph, telephone or wireless, our American cousins, in complete ignorance as to the details of what was afoot, though moving towards a similar goal, founded the American Unitarian Association on precisely the same day—May 26, 1825."[3]

The AUA's official journal was The Christian Register (1821–1961).
