History & Origin

Leo comes directly from the Latin leo (lion), a symbol of strength, courage, and royalty across many cultures. It has been used as both a given name and a title of power since ancient Rome, and the lion has been a central symbol in European heraldry for over a millennium.

The name was borne by thirteen Roman Catholic popes, several Byzantine emperors, and was a common name in medieval Europe. It declined somewhat in the 19th and early 20th centuries, then began a strong revival in the late 20th century. Leo entered the U.S. top 20 boys' names around 2017 and has continued rising.

Did you know? Thirteen popes bore the name Leo, including Leo I 'the Great' (died 461 AD), who reportedly persuaded Attila the Hun to turn back from Rome, and Leo III, who crowned Charlemagne as Holy Roman Emperor on Christmas Day 800 AD.
