Ethnoreligious groups in the United States

The Huguenots ( , ; ) are a religious group of French Protestants who held to the Reformed (Calvinist) tradition of Protestantism. The term, which may be derived from the name of a Swiss political leader, the Genevan burgomaster Besançon Hugues, was in common use by the mid-16th century. Huguenot was frequently used in reference to those of the Reformed Church of France from the time of the Protestant Reformation. By contrast, the Protestant populations of eastern France, in Alsace, Moselle, and Montbéliard, were mainly Lutherans.

The Molokans ( or , "dairy-eater") are a Russian Spiritual Christian and a Protestant sect that evolved from Eastern Orthodoxy in the East Slavic lands. Their traditions, especially dairy consumption during Christian fasts, did not conform to those of the Russian Orthodox Church, and they were regarded as heretics (). The term is an exonym used by their Orthodox neighbors. Members tend to identify themselves as Spiritual Christians (, ).
