Finnan is a modern take on an old Irish surname, first appearing in U.S. birth records in 2005. As of 2025, it ranks 2884, with a 1-in-39,723 rate of use among boys. Its popularity has been rising since 2017, and it reached its peak rank so far in 2023. The name remains relatively rare, with no concentration in any particular state, appealing to parents seeking an Irish-inspired name that feels fresh but not overly common.
Finnan is likely a transferred use of the Irish surname Ó Fionnáin, which derives from the given name Fionnán, a diminutive of fionn meaning 'fair' or 'white'. The name has been used in Ireland for centuries as a surname, and its adoption as a first name in the United States is a modern development, first recorded in the Social Security data in 2005.
