Neenan is Irish in Origin.

Neenan (pronounced NEE-nən) is a rare surname-turned-given name of Irish origin. It is often linked to the Gaelic Ó Naoimhín, “descendant of Naoimhín,” a diminutive of naomh, “holy, saintly,” yielding the sense “little saint” or “holy one.” The same root underlies Anglicized forms such as Nevin and Niven, and relates to the Irish given name Naoimhín.

As a family name, Neenan appears in Munster and Connacht records from the 18th–19th centuries; as a first name, it has emerged more recently in the English-speaking world, aligning with the trend of distinctive, surname-based choices. Variant and related forms include Nevin, Neavyn, and Niven; some lines also connect Neenan with Heenan, from Ó hÉanáin, built on éan, “bird,” meaning “little bird.” Usage remains uncommon and broadly unisex. Informal short forms like Nee or Nan occur, though the full two-syllable name is typically preferred.
