DeLancey Divinity School was a seminary of the Episcopal Church in the United States of America located in Geneva, New York, and Buffalo.
It was founded in 1850 by William Heathcote DeLancey (1797-1865), first Bishop of the Episcopal Diocese of Western New York as a diocesan seminary at Geneva.
On February 1, 1861, Bishop DeLancey opened a new diocesan school at Geneva under the direction of the Rev.
DeLancey acquired the library of St. Andrew's Divinity School (Syracuse) in 1906.
The centenarian Episcopal priest John Robert Jackson (1913-2013) was believed to be the last living alumnus of DeLancey Divinity School.
