Domitian of Huy (Latin: Domitianus; also, of Maestricht) was a Gaulish bishop of the sixth century who is noted for both his generosity and writings against heresy.

[2] He encouraged the development of polemic against heresy in the early church, and worked to evangelize the Meuse Valley.

Domitian also constructed churches and hospices in order to care for people spiritually and physically.

He was well known for his generosity, as well as his ability to procure money via fund-raising, a talent that once helped to ease a famine in his bishopric.

[2] Domitian's relics are kept and venerated at the Church of Notre-Dame in Huy, Belgium, the city of which he is now the patron saint.
