Finn is the modern form of the Irish Fionn and means "fair" or "white"; Fionn mac Cumhaill is the great hero of Irish legend, leader of the warrior band Fianna. In America the name also belongs to Mark Twain's Huckleberry Finn, which gives it a tousled, adventurous spirit. Finn has been in the US top 1000 since 2000, when it ranked number 836; it has sat in the top 210 every year since 2015, peaked at number 166 in 2018 and stands at number 206 in 2025.
