Lúighne is a territory in Íochtar Connacht, now County Sligo, Ireland. It is now represented by the barony of Leyny.

Leyney (Luíghne) is a barony in central Co. Sligo. It corresponds to the ancient túath of Luíghne.

Muimne, Luigne and Laigne, sons of Érimón by his wife Odba, were, according to medieval Irish legends and historical traditions, joint High Kings of Ireland following the death of their father. They ruled for three years, until Muimne died of plague at Cruachan, and Luigne and Laigne were killed by their cousins Ér, Orba, Ferón and Fergna, sons of Éber Finn, in the Battle of Árd Ladrann, leaving no heirs. The Lebor Gabála Érenn synchronises their reign to the last year of Mithraeus and the first two years of Tautanes as kings of  Assyria (1192-1189 BC, according to Jerome's Chronicon). Geoffrey Keating dates their reign from 1272 to 1269 BC, the Annals of the Four Masters from 1684 to 1681 BC.
