Meaning & origin

Llewyn is a rare modern Welsh name that first appeared on the U.S. charts in 2014. It reached a peak rank of 4,139 in 2022, but has been declining in use since 2021, with the trajectory labeled as falling. The name is often associated with the protagonist of the Coen Brothers' 2013 film 'Inside Llewyn Davis', which likely contributed to its initial popularity. Despite its cinematic tie, Llewyn remains an uncommon choice, with an estimated 1 in 68,323 newborns receiving the name in 2025. The name has not been recorded in any top states, suggesting its usage is spread thinly across the country. Llewyn's short history and rarity make it a distinctive and modern pick for parents seeking a Welsh-inspired name without traditional baggage.

Llewyn is a rare Welsh name, likely a modern variant of the more traditional Llewellyn, which derives from the Welsh name Llywelyn. The exact meaning of Llywelyn is debated; it may come from llyw 'leader' or a compound with llew 'lion'. Llewyn emerged as an independent given name in recent years, possibly influenced by the prominence of singer-songwriter Bob Dylan's fictional character in the 2013 film 'Inside Llewyn Davis'.
