Malachy of Ireland (fl. 1279–1300), also known as Malachias Hibernicus, was a theologian and Archbishop of Tuam in 1280. He was a friar of the Franciscan convent of Limerick and was elected Archbishop of Tuam, though never officially installed. He was first mentioned in a letter of 1279 from , Archbishop of Armagh, to Edward I of England, Lord of Ireland, asking that Brother Malachy be appointed to Tuam. The king granted this request in a letter dated 22 April 1280. However, five of the seven canons of Tuam chosen as electors voted for Nicol Mac Flainn, a fellow canon. This resulted in Stephen de Fulbourn being transferred from Waterford to Tuam. Malachy had by then abandoned his claim, and his election was annulled.
