James Mumford

James Mumford (c.1606 – 9 March 1666) was an English Jesuit priest and Catholic controversialist.

Born in Norfolk or Suffolk, Mumford joined the Society of Jesus in 1626 in which he was ordained priest at Liège around 1635. He made his final Jesuit profession in 1641. He taught in the Jesuit colleges at St Omer, Watten, and Liège, where he was elected rector in 1648. He returned to England in 1650, based in Norwich as a member (and possibly later rector) of the Jesuit College of the Holy Apostles, which comprised the Jesuits' English mission to eastern counties.

Aside from his controversial writings, Mumford wrote several works on purgatory.
