What is the meaning of the name Naoise ?

Naoise is Irish in Origin.

From Irish Gaelic, Naoise (commonly pronounced NEE-sha) descends from Old Irish Noísiu, the name of the tragic hero loved by Deirdre in the Ulster Cycle. The tale’s wide retelling, including the play Deirdre of the Sorrows, kept the name alive in literary and nationalist circles and aided its 20th-century revival. While borne by a male hero, modern usage in Ireland and Scotland is often unisex, though statistical records still skew male.

Scholars view the etymology as uncertain; folk glosses render it “warrior,” “champion,” or simply “hero,” influenced by the legend rather than firm linguistic roots. Documented variants and anglicizations include Noísiu and Naisi in older texts, and phonetic spellings such as Neesha or Neisha in English-speaking contexts. An informal nickname is Neesh. Related surnames have not developed, and the name retains a strong mythic Irish identity.
