Níall of Carrick (also Neil) was the second man to bear the title Mormaer, or Earl, of Carrick. He was successor of mormaer Donnchadh of Carrick. He may have been Donnchadh's son, or else as suggested by one recent genealogical theory, his grandson. It has been argued that Niall's father was Nichol (Cailean or Colin), son of mormaer Donnchadh by the daughter of Niall Ruadh, briefly king of Tir Eoghain.
On 12 September 1255 Níall, having no male heirs, granted the chiefship of the clan to his nephew Roland and his heirs, giving them all the powers in respect to the ceann ceneóil (head of kin). This grant was confirmed by King Alexander III at Stirling in 1276.
