Domhnall is Irish, Scottish Gaelic in Origin.

A Gaelic royal name with deep roots, Domhnall comes from Old Irish Domnall, likely built from Proto-Celtic elements *dumno- “world, deep” and *walos “ruler, mighty,” yielding the sense “world-ruler” or “mighty ruler.” In modern Irish spelling, the lenited mh reflects an earlier sound now often silent, giving pronunciations close to Donal/Donald. Related Gaelic forms include Irish Domhnall and Dónall and Scottish Gaelic Dòmhnall; Old Irish Domnall appears in early annals.

The name was borne by numerous rulers and nobles across the Gaelic world, including High Kings of Ireland (e.g., Domnall mac Áeda) and medieval kings of Scotland (Domnall Bán, Donald III). It underlies major surnames and clans: Mac Domhnaill (MacDonald/MacDonnell) and Ó Domhnaill (O’Donnell). Anglicised variants are Donald, Donal, and Donnell, with nicknames Don, Donnie, and Donny. Usage remained strong in Scotland and Ireland and spread broadly via Donald in the 19th–20th centuries.
