More than one thousand congregations in the United States and Canada belong to the Unitarian Universalist Association (UUA) of Congregations, with headquarters in Boston, Massachusetts.

The oldest Unitarian congregations are in Romania. There are large Unitarian congregations in the Khasi Hills of India. Others are found in Hungary, the Czech Republic, Poland, Germany, France, Great Britain, Australia, Nigeria, South Africa, the Philippines, and Japan. (Some of these are Unitarian and some are Universalist.)

North American Unitarian Universalists maintain ties with other Unitarian Universalists throughout the world, mostly through our membership in the International Association for Religious Freedom (IARF), organized in 1900. Members of the IARF include other liberal Christian groups as well as Humanist, Hindu Reform, Shinto, and Buddhist groups.

USNH serves the communities in the Greater New Haven, Connecticut area.  To find other congregations throughout the U.S. and Canada, please click here.
