Ruaidhrí Mac Ruaidhrí was a fourteenth-century Scottish magnate and chief of Clann Ruaidhrí. He was an illegitimate son of Ailéan mac Ruaidhrí, and is recorded to have participated in the kindred's military actions against supporters of both the English Crown and Scottish Crown. Following the apparent death of his brother, Lachlann, Ruaidhrí appears to have taken control of the kindred, and firmly aligned the family with Robert I, King of Scotland. Ruaidhrí may well be the member of Clann Ruaidhrí who is recorded slain at the Battle of Faughart in support of the Bruce cause in Ireland. After his death, Ruaidhrí's half-sister, Cairistíona, attempted to transfer the Clann Ruaidhrí territories outside the family. Ruaidhrí was survived by a daughter, Áine, and an illegitimate son, Raghnall. The latter fended off Cairistíona's actions and succeeded to the chiefship of Clann Ruaidhrí.

Clann Ruaidhrí was a leading medieval clan in the Hebrides and the western seaboard of Scotland. The eponymous ancestor of the family was Ruaidhrí mac Raghnaill, a principal member of Clann Somhairle in the thirteenth century. Members of Clann Ruaidhrí were factors in both the histories of the Kingdom of the Isles and the Kingdom of Scotland in the thirteenth- and fourteenth centuries. The family appears to have held power in Kintyre in the thirteenth century. By the fourteenth century, the family controlled an extensive provincial lordship stretching along north-western Scottish coast and into the Hebrides. As a leading force in the Kingdom of the Isles, the family fiercely opposed Scottish authority. With the collapse of Norwegian hegemony in the region, the family nimbly integrated itself into the Kingdom of Scotland.
Now-ruinous Castle Tioram may well have been a Clann Ruaidhrí stronghold. The island the fortress sits upon is first recorded in a charter of Cairistíona Nic Ruaidhrí. According to early modern tradition, the castle was erected in the fourteenth century by her niece, Áine Nic Ruaidhrí. The castle served as the seat of the latter's Clann Domhnaill descendants for the next four hundred years.
