Áed in Macáem Tóinlesc or Aodh an Macaoimh Tóinleasg (died 1177) was a 12th-century ruler of Tulach Óc and Tír Eogain. He was the first of his family to play a significant role in the high politics of northern Ireland, following the death of the Muirchertach Mac Lochlainn king of Tír Eogain and high king of Ireland.

With the help of Donnchad Ua Cerbaill, king of Airgíalla, Áed was able to become king of Tír Eogain himself, though for much of the time he was forced to share the position with a Meic Lochlainn. Áed secured his hold on kingship partly by submitting to the Connacht high king Ruaidrí Ua Conchobair. As one of the latter's chief vassals, he was involved in the early stages of resistance to the Anglo-Norman invasion of Ireland.
