Donnaly is Irish in Origin.

Donnaly is a modern given name with Irish roots, reshaped from the surname Donnelly. That surname goes back to the Gaelic Ó Donnghaile/Ó Donnghalaigh, meaning “descendant of Donnghal.” The old personal name Donnghal joins donn, “brown, dark,” with gal, “valor, might,” yielding readings such as “brown‑haired warrior” or “one of steadfast courage.” By adopting a lighter -aly ending, Donnaly keeps the heritage while sounding contemporary and approachable.

As a first name, Donnaly follows the wider Anglophone trend of turning surnames into given names, and it appears sporadically from the late 20th century onward in Ireland, Britain, and the Irish diaspora in North America. Variant spellings include Donnelly, Donnally, Donally, and Donaly; Donnelly remains most common. It is used for all genders, though the -aly ending can skew it slightly feminine. Related but distinct: Donal/Dónal (from Domhnall).
