O'Leary is an Irish surname derived from the Gaelic Ó Laoghaire, meaning "descendant of Laoghaire"—a personal name often interpreted as "keeper of the calves" or "calf herder." The name is historically associated with a prominent family lineage in County Cork, Ireland, where the O'Learys were chieftains in the ancient kingdom of Munster. Over time, individuals bearing the O'Leary surname have become notable in various fields such as politics, military service, literature, and religion, both in Ireland and abroad.

to settle in Ireland from 500 to 100 BC. The port of Dún Laoghaire, near Dublin is not associated with the O'Leary sept(s), rather it is named for Lóegaire mac Néill, a 5th-century High King of Ireland. The book of Lecan (A.D. 1397-A.D. 1418) details the early status of O'Leary as a Corco Laide ''taisach duchusa'' (hereditary chieftain) in the tuath of Ross (Ruis), with associated families:

Tuath Ruis .i. Tuath in Dolaich, o Loch in Bricin co Faid Ruis -, o Thraig Long co Sid na Fear (i) Find. O Leagaire a taisach duchusa. Is iad so an oclaid duchusa .i. O Ruaidri -, O Lonan -, O Laidid -, O Torpa -, O hUrmoltaich -, O Mirin -, O Meic Dairic -, O Tuaraide -, O Trena -, O hUainidi -, O Cerdin

The name also occurs in the Cineal Laoghaire branch of the Eoghanacht dynasty which later came to dominate Munster. With the unrelated Corco Laidhe and Eoghanacht branches of O'Learys settling in north-west Cork and nearby Kerry respectively, the tracing of lineage is complex.
