Richard Fish Cadle (April 17, 1796 – November 9, 1857) was an American Episcopalian priest and the first superior of Nashotah House.
In 1824, Cadle was sent to Detroit, Michigan Territory where he started St. Paul the Apostle Church.
He resigned in 1843 and was a missionary in Wisconsin Territory serving in Prairie du Chien, Mineral Point, Whitewater, and Green Bay.
In 1841, Bishop Jackson Kemper named Cadle superior of the fellowship which resulted in the Nashotah mission and Nashotah House; he felt unsuited as superior of Nashtotah House and resumed his missionary work.
In 1844, he retired from being a missionary and served churches in New York, Vermont, and Delaware.
