Meaning & origin

Jullien is a rare modern variant of Julien, the French form of Julian. The name first appeared in U.S. birth records in 1991, which is relatively recent for a name with ancient roots. Its peak year came in 2009, when it saw its highest usage, though it has been on a downward trajectory since 2010. Jullien has never ranked among the top 1,000 names, and its one-in-N rate is not available due to its rarity. The name has not been associated with any particular state or region, as it has not appeared in the top names for any state. As a modern respelling, Jullien reflects a trend of phonetic and stylish variations of established names. Its spelling gives it a distinctive, almost French flair, yet it remains firmly a product of contemporary American naming practices.

Jullien is a modern variant spelling of Julien, the French form of the Latin name Julianus, derived from Julius. The name has been used in English-speaking countries since the late 20th century, often as a distinctive respelling. The variant Jullien appears to have gained some traction in the United States beginning in the 1990s, likely influenced by the popularity of similar-sounding names like Julian.
