"Mo Ghile Mear" (translated "My Gallant Darling", "My Spirited Lad" and variants) is an Irish song. The modern form of the song was composed in the early 1970s by Dónal Ó Liatháin (1934–2008), using a traditional air collected in Cúil Aodha, County Cork, and lyrics selected from Irish-language poems by Seán "Clárach" Mac Domhnaill (1691–1754).
