Renowned warrior
Lou originated as a short form of Louis or Louise, which are derived from the Germanic name Ludwig. The name combines the elements 'hlud' (famed or loud) and 'wig' (warrior). While traditionally a nickname, it has gained independent use as a minimalist, gender-neutral choice.
About 81 boys were named Lou in 2025.
