Daniel Fitter (born in Worcestershire, England, 1628; died at St. Thomas' Priory, near Stafford, 6 Feb., 1700) was an English Catholic clergyman who was affected by but managed to navigate his way through the religious strife of the late seventeenth century.
In consequence of this, when the chapter chose him as Vicar-General of the Counties of Staffordshire, Derbyshire, Cheshire and Salop, they required that he should "sign a Declaration made by our Brethren in Paris against the Oath of Supremacy".
In a letter to the clergy of England and Scotland (1684), Cardinal Philip Howard recommended warmly the "Institutum clericorum in communi viventium", founded in 1641 by the German priest Bartholomew Holzhauser, and approved by Innocent XI in 1680 and 1684.
The institute met with eager acceptance in England, and Fitter was appointed its first provincial president and procurator for the Midland district.
Daniel Fitter also left a fund for the maintenance of a priest, whose duty it should be to reside in the county of Stafford and take spiritual charge of the poor Catholics of the locality.
