Dubricius or Dubric (Welsh: Dyfrig; Norman-French: Devereux; c. 465 – c. 550) was a 6th-century British ecclesiastic venerated as a saint.

[4] He became the teacher of many well-known Welsh saints, including Teilo and Samson and also healed the sick of various disorders through the laying on of hands.

He later became Bishop of Ergyng,[4] possibly with his seat at Weston under Penyard, and probably held sway over all of Glamorgan and Gwent, an area that was later known as the diocese of Llandaff.

According to legend, Dubricius was made Archbishop of Llandaff by Saint Germanus of Auxerre, and later crowned King Arthur.

He appears as a character in Geoffrey of Monmouth's Historia Regum Britanniae and Wace's Roman de Brut, which was based on it.
