Oonagh is Irish in Origin.
Rooted in Irish Gaelic, Oonagh reflects the name Úna (Irish: Úna; Scottish Gaelic: Ùna), commonly Anglicised as Oona, Oonagh, and Una. Variant spellings Oonagh and Oona are frequent in Ireland and the diaspora; Una is the streamlined English form. It is traditionally derived from Irish uan, “lamb,” giving the name associations of gentleness and protection. While sometimes linked by meaning to Agnes or by sound to Latin una “one,” the Irish origin is distinct.
Úna appears in medieval annals and poetry, remained steady in Gaelic-speaking communities, and features in folklore as Queen Úna, bride of Finvarra, the fairy king of Connacht. The name saw renewed visibility during the Irish cultural revival and internationally through figures like Oona O’Neill (Lady Chaplin). Today Oonagh retains a distinctly Irish flavor while remaining accessible across languages.
