Donnchad mac Gilla Pátraic (Donagh MacGillapatrick) (died 1039), was King of Osraige and King of Leinster.
His father was Gilla Pátraic mac Donnchada. He took the throne of Osraige prior to 1027 and was active militarily. He blinded his brother Tadc, thus eliminating him from succession. King Donnchad inflicted a slaughter on the Dál gCais and Eóganachta, led by Donnchad mac Briain in a predatory incursion into Osraige.[1][2] Brian's son launched a second expedition into Osraige again in 1031, in which he was again defeated by Mac Gilla Pátraic.[3] Mac Briain was successful in his third attack on Osraige in 1034.[4]
He took the throne of Leinster in 1033 and held the Fair of Carman, a prerogative of the kings of Leinster.[5]
In 1039, Donnchadh led a combined force of Ossorians and the Leinstermen, raiding and burning as far as Knowth and Drogheda.[6] The Annals of Tigernach eulogize him as "overking of Leinster and Ossory, champion of Ireland".[7]
