Flynn is an Irish surname, from Ó Floinn, built on flann, "red" or "ruddy", originally a nickname for someone with red hair or a ruddy complexion. Hollywood swashbuckler Errol Flynn and the charming thief Flynn Rider in Disney's Tangled (2010) gave it dash. Flynn entered the US top 1000 in 2011, the year after Tangled, peaked at number 654 in 2021 and ranks number 828 in 2025.
