Thomas Richey (November 1, 1831 — June 3, 1905) was a prominent Irish-American Anglo-Catholic priest, professor, and author in the Episcopal Church.
He was born in Newry, County Down, in Ireland and had settled in Pittsburgh by 1847, following his graduation at 16 from Queen's College, Belfast.
He was graduated from the General Theological Seminary of the Episcopal Church in 1854 and ordained to the priesthood by Bishop Horatio Potter in 1855.
The seminary's board of trustees requested his resignation on the grounds of infirmity in 1902; Richey declined the offer of a pension and insisted on retirement at half salary with status as professor emeritus.
His brother Joseph Richey was also a major Anglo-Catholic clergy figure in Baltimore, who is now included in the Lesser Feasts and Fasts of the Episcopal Diocese of Maryland.
