History & Origin

Ruari is one of several spellings of Gaelic Ruaidhri (Ruairi, Ruaridh, Rory), built from ruadh ('red') and ri ('king'). It was borne by kings and clan chiefs across Ireland and the Scottish Highlands, most famously Ruaidhri Ua Conchobair, the last High King of Ireland. This trimmed spelling keeps the sound while easing the reading (said 'ROO-uh-ree').

It appears only rarely in the U.S., though it is familiar in Ireland and Scotland. Rare here, rooted, and Gaelic.

Did you know? Ruari is the Gaelic name that gave English Rory: ruadh, 'red', plus ri, 'king'. Ruaidhri Ua Conchobair, who died in 1198, was the last High King of Ireland — so the name carries real history.
