The Kings of Luighne Connacht were rulers of the people and kingdom of Luighne Connacht, located in what is now County Mayo and County Sligo, Ireland.

The southern area was originally known as Gailenga but by the 12th-century called Sliabh Lugha. After the Anglo-Norman conquest of Connacht, it was known as the barony of Gallen, and ruled by the clan Mac Siúrtáin until the early 17th century.

The northern area, lying in south-west County Sligo, retained the name Luighne.

The families of Ó hEaghra, Ó Gadhra and Devlin of Connacht descend from rulers of the kingdoms.
