Dalbhach (Lat. Dalmacius), an Irish saint of CouilCollainge, lived about the first half of the 7th century. He was of the race of Oilill Flaunbeg, a disciple of St. Abban and a friend of St. Caiman. He was a strict performer of penance, and it is said that "he never touched his hand to his side as long as he lived." He is commemorated October 23.
