Feargus Origin and Meaning

The name Feargus is a boy's name.

Feargus is a masculine name of Irish Gaelic origin, derived from 'fear' meaning 'man' and 'gus' meaning 'vigor' or 'strength,' combining to mean 'strong man' or 'man of vigor.' This powerful name was borne by several kings and heroes in Irish mythology and history, including Feargus mac Róich, a legendary warrior in the Ulster Cycle. Though relatively uncommon in modern usage outside of Ireland and Scottish Gaelic-speaking regions, the name carries deep cultural significance and represents Celtic heritage. Feargus offers a distinctive alternative to the more common Fergus spelling, maintaining its authentic Gaelic roots while providing a strong, masculine option with historical depth.
