Giolla Críost Brúilingeach (fl. 1440) was a noted Scottish harper and poets. He was mentioned in the Book of the Dean of Lismore, which possibly identifies him with Leim of Gigha, and with the MacBhreatnaigh (Galbraiths) of that island.
His poetry includes Scottish and Irish subjects, including one to Conochobar Óg MacDiarmada of Moylurg (1458), a chief in Connacht, requesting a new harp as a fee.
