James DeKoven (September 19, 1831 – March 19, 1879) was a priest, an educator and a leader of Anglican Ritualism in the Episcopal Church.

He accepted a teaching position at Nashotah House in Wisconsin and became rector of the nearby St. John Chrysostom parish in Delafield.

[2][3] According to his opponents, his views on transubstantiation "were generally understood to approximate more closely to Romanism than the language of the Thirty-Nine Articles admitted.

After suffering a fall on the ice, De Koven died on Saint Joseph's Day (March 19) in 1879.
