Meaning & origin

Loui is a variant spelling of Louie, a French diminutive of Louis. First recorded in the U.S. in 1990, it saw a modest peak in 2021, ranking at its highest point before a gradual decline from 2022 onward. Its current incidence of 1 in 213,510 births places it as a rare but recognized alternative to the more common Louis or Louie. Top state data is limited due to low numbers, but its usage is scattered across the country. The name's Germanic roots, meaning 'famous warrior', connect it to centuries of European royal and noble tradition, yet its modern spelling gives it a fresh, concise feel.

Loui is a variant spelling of Louie, which is a French diminutive of Louis. Louis derives from the Germanic name Chlodowig, composed of the elements hlud (famous) and wig (war). It has been a common name among French royalty.
