History & Origin

Knox is a Scottish and English surname derived from Old English cnoc ('knoll, hillock, round hill'). The most famous historical bearer is John Knox (c. 1514–1572), the Scottish minister who led the Protestant Reformation in Scotland. The Jolie-Pitt naming in 2008 significantly boosted its use as a first name.

Knox entered the U.S. top 500 boys' names in the 2000s and climbed rapidly after 2008. Its single-syllable force, historical weight, and current stylishness make it one of the most fashionable short boys' names. It sits comfortably with similarly punchy names like Jett, Cole, and Colt.

Did you know? Angelina Jolie and Brad Pitt named their son Knox in 2008 — the same year they named a daughter Vivienne — bringing this Scottish reformer's surname into the 21st-century baby name charts.
