What is the meaning of the name Una ?

The baby name Una is a Female name , 2 syllables long and is pronounced OO-nah (/ˈuːnə/); occasionally YOO-nah (/ˈjuːnə/).

Una is Irish in Origin.

Una is a feminine given name with two intertwined sources. In Irish and Scottish Gaelic it appears as Úna/Ùna, derived from Old Irish uan, “lamb,” a tender pastoral image that made the name popular in medieval Gaelic families and folklore (notably the clever wife Oonagh in tales of Fionn mac Cumhaill). In literary Latin and English it echoes una, “one; unity,” a resonance cemented by Edmund Spenser’s The Faerie Queene, where Una personifies truth and oneness.

Usage persisted in Ireland into the 19th century and was Anglicized as Una, Oona, Oonah, and Oonagh; modern spellings include Úna (Irish standard) and Ùna (Scottish). The name enjoyed wider Anglophone notice through Oona O’Neill Chaplin in the mid-20th century and has since seen periodic revival, appreciated for its simple two-syllable form, Gaelic heritage, and dual meanings of “lamb” and “unity.”
