What is the meaning of the name Ruailidh ?

Ruailidh is Scottish Gaelic in Origin.

Ruailidh is a rare Scottish Gaelic spelling variant of Ruairidh, cognate with Irish Ruairí and ultimately descending from Old Irish Ruaidrí (from ruad “red, russet” + rí “king”). The meaning is “red king,” often interpreted as “red‑haired king.” Spelling fluctuation in Gaelic - especially around slender consonants - has produced forms such as Ruairidh, Ruaraidh, and Ruaidhrí; Ruailidh reflects that orthographic variation found in historical and regional usage.

The name was common in the medieval Gaelic world among chieftains and nobles, and its Irish counterpart Ruairí appears in the annals (e.g., Ruairí Ua Conchobair, last High King of Ireland). In Scotland it has persisted in the Highlands and saw modern revival alongside Gaelic cultural renewal. Established variants include Ruairidh, Ruaraidh (Scots Gàidhlig), Ruairí/Ruairí (Irish), and Ruaidhrí (older). Anglicized forms are Rory, Rorie, Ruari, and Ruaridh; Rory is now unisex in English, though the Gaelic forms remain traditionally masculine.
