Fin

Meaning & origin

Fin is a concise and modern name that has been in use since 2003, when it first appeared in U.S. data. Its popularity has been rising steadily since 2007, reaching a peak in 2019. In 2025, it ranked 7194th for boys, with an estimated rarity of 1 in every 155,280 boys born that year. While primarily used as a short form of the Irish name Fionn, meaning 'fair' or 'white', Fin also functions as a diminutive of Finley or Finnegan, and sometimes as a straightforward word name. Its simple sound and two-letter spelling make it easy to pronounce and spell, though it may be most familiar as a nickname rather than a full given name. The name has no strong association with any top states in the data, suggesting it is used broadly but not regionally concentrated.

Fin is a short form of the Irish name Fionn, borne by the legendary warrior Fionn mac Cumhaill, meaning 'fair' or 'white'. In modern usage, it also serves as a diminutive of Finley or Finnegan, and has gained traction as an independent given name. Since the early 2000s, Fin has been used as a standalone name in English-speaking countries, sometimes inspired by the English word 'fin', as in a fish's fin.
