Fearghus Origin and Meaning

The name Fearghus is a boy's name.

Fearghus is a masculine name of ancient Irish and Scottish Gaelic origin, a variant of Fergus, which derives from the elements 'fear' meaning 'man' and 'gus' meaning 'vigor, force, or choice'. Historically, it was the name of several important figures in Celtic mythology and early Irish history, including Fergus mac Róich, a legendary king of Ulster. The name carries connotations of masculine strength, bravery, and leadership. While traditional in Ireland and Scotland, Fearghus remains relatively uncommon in the broader English-speaking world, preserving its distinctive Celtic character. Parents choosing this name often appreciate its strong historical roots, authentic Gaelic form, and the powerful yet melodic sound.
