Scottish Gaelic form of Richard, also found as Risteard.

Ruaraidh is a feminine name of Scottish Gaelic origin, being the feminine form of the masculine name Ruairidh (Rory). It means "red king" or "famous ruler," derived from the Gaelic elements "ruadh" (red) and "righ" (king). While traditionally a male name in Scotland, this feminine variant is quite rare. The name carries strong Celtic heritage and connections to Scottish clan history. The pronunciation can be challenging for non-Gaelic speakers, typically sounding like "ROO-uh-ree." Despite its ancient roots, Ruaraidh remains uncommon in contemporary usage outside of Scotland and families with strong Scottish heritage.
