Diminutive of Louis or Lewis, French and German
"renowned warrior"

Lou Origin and Meaning

The name Lou is a boy's name of German, French origin meaning "renowned warrior".

Lou, all by itself, is become fashionable for girls, which usually makes a name LESS fashionable for boys. But Lou, like Bill or Jim, is rarely used on its own for boys anyway. (You wouldn't name a boy Frederick Lou the way that girls are named Mary Lou or, in the case of Keri Russell's new baby, Willa Lou.) Long form Louis is getting cool again and, with the Lewis spelling, is the Number 2 name in Scotland.
