Rorie is a girls' spelling of Rory, the anglicized form of the Irish and Scottish Ruaidhrí, which means "red king" or "red-haired king", from ruadh, red, and rí, king. The -ie ending gives it the look of Rosie and Romy and marks it as feminine, while Rory remains unisex. Rorie was almost unused in 2000 at number 17035, moved into the 3000s during the 2010s and reaches its best rank, number 2452, in 2025 with 73 girls.
