Louie spells out the English pronunciation of Louis, the French royal name that comes from the Germanic Hludwig and means "famous warrior" or "renowned in battle". Long treated as a nickname, it is now given on its own, encouraged by the British taste for cozy forms like Alfie and Archie. Louie entered the US top 1000 in 2015, peaked at number 573 in 2024 and ranks number 596 in 2025.
