The Kings of Umaill were rulers of Umaill, a kingdom or territory located in the west of what is now County Mayo, Ireland.

Its earliest rulers were the semi-historical Tuath mhac nUmhoir. The Umaill, its early historical rulers, were renamed the Uí Briúin Umaill to claim a fictitious relationship with the Uí Briúin. By the 12th century the ruling family adopted the surname Ó Máille, and were reckoned with the Ó Dubhda, Ó Flaithbheartaigh and Mac Conraoi as supreme seafaring clans of Connacht.
