Mael Fabhaill mac Cléirigh

Mael Fabhaill mac Cléirigh (died 887) was the King of Uí Fiachrach Aidhne in Ireland.

Mael Fabhaill was one of the last kings of Aidhne who did not use a surname. His son and successor, Tighearnach Ua Cleirigh, did so and was ancestor to the family of Ó Cléirigh.

Mael Fabhaill had a brother, Eidhean mac Cléirigh, who gave his name to the Ó hEidhin family of south County Galway.
