Mugrón mac Flainn (died 782) was a king of the Uí Failge, a Laigin people of County Offaly. He was one of the many sons of Fland Dá Chongal, a previous king.Mac Niocaill, pg.127 He ruled from 770 to 782.In the Book of Leinster king list he is given a reign of 25 years. He was the third of Fland's sons by Érenach, daughter of Murchad Midi (died 715) of Uisnech, to hold the throne.
Mugrón aligned with Bran Ardchenn mac Muiredaig (died 795), claimant to the Leinster throne (who was also allied to the high king Donnchad Midi) versus the incumbent king Ruaidrí mac Fáeláin (died 785). They were however defeated at the Battle of Curragh (near Kildare) and Mugrón was slain.Annals of Ulster, AU 782.3; Byrne, pg.158
