Aedh Buidhe (died 600, "Áed the Yellow") was the 13th King of the Uí Maine.
The early historic era of the kingdom of Uí Maine is fragmentary.
King Brenainn mac Cairbre died in 597 and it is presumed that Aedh Buidhe succeeded him.
The Annals of the Four Masters, based on earlier sources, state that Aedh was killed on the same day that King Áed Sláine of Brega killed Áed Rón mac Cathail of the Ui Failghe, whose death is however set at 604.
