Lóegaire (Loeguire, Láegaire, Laoghaire, sometimes anglicised as Leary), son of Niall of the Nine Hostages.

Lóegaire was a semi-legendary High King of Ireland and succeded his father Niall Noigíallach. Four years into this reign St. Patrick appeared in Ireland. He is believed to have died about 463 or 464 after a reign of about ten years.

In Muirchu 's 7th century Life of Patrick, Loeguire is described as "a certain great, fierce, pagan emperor of the barbarians reigning in Tara." He is said to have being killed by a lightning flash at Greallach Dabhaill beside the Liffey. He was the father of the High King Lughaid mac Loeguire.
