The Orthodox Christian Reformed Churches (OCRC) were a theologically conservative federation of churches in the Dutch Calvinist tradition. Although the federation has disbanded, most of its churches still exist. They are in the United States and Canada. They confess the Bible to be the Word of God and believe it is faithfully summarized by the Belgic Confession, Heidelberg Catechism, and Canons of Dort.

In addition to the four mentioned above, there were congregations in Bowmanville, Ontario (1982); Cambridge, Ontario (1984); and Ripon, California (1985).

The OCRC federation had two decades of stability and then a decade of decline. In 2004 the Listowel congregation joined the Protestant Reformed Churches in America.
