Meaning & origin

Gwynn is a Welsh name with deep roots in Celtic mythology, meaning 'white, fair, or blessed'. It first appeared in the US records in 1923 and attained its peak popularity in 1949. In 2025, it ranked 7885th, with an estimated 1 in 123,636 newborns receiving the name. Its trajectory has been falling since 2015, reflecting a shift away from less common traditional names. While Gwynn has not been strongly associated with any particular US state in recent years, it retains a connection to Welsh heritage. The name's rarity today offers a distinctive choice for parents seeking a name with ancient linguistic and mythological ties.

Gwynn is a Welsh name derived from the word 'gwyn', meaning 'white, fair, blessed'. It originated as a given name and also as a surname, historically borne by many notable figures in Wales. In Welsh mythology, Gwynn ap Nudd is a king of the fairy Otherworld. The name saw a modest revival in the 20th century as a feminine given name, though it remains relatively rare.
