Ímar mac Arailt was an eleventh-century ruler of the Kingdom of Dublin and perhaps the Kingdom of the Isles. He was the son of a man named Aralt, and appears to have been a grandson of Amlaíb Cuarán, King of Northumbria and Dublin. Such a relationship would have meant that Ímar was a member of the Uí Ímair, and that he was a nephew of Amlaíb Cuarán's son, Sitriuc mac Amlaíb, King of Dublin, a man driven from Dublin by Echmarcach mac Ragnaill in 1036.
Ímar's name it appears on folio 17r of Oxford Bodleian Library Rawlinson B 488 (the Annals of Tigernach): "h-Imar mac Arailt".

Echmarcach mac Ragnaill was a dominant figure in the eleventh-century Irish Sea region. At his height, he reigned as king over Dublin, the Isles, and perhaps the Rhinns of Galloway. The precise identity of Echmarcach's father, Ragnall, is uncertain. One possibility is that this man was one of two eleventh-century rulers of Waterford. Another possibility is that Echmarcach's father was an early eleventh-century ruler of the Isles. If any of these identifications are correct, Echmarcach may have been a member of the Uí Ímair kindred.

Ruinous Cruggleton Castle from a distance. The fortress was likely a power centre of later Lords of Galloway, and could have been a seat of Echmarcach himself.
