Leo

US Popularity:30
Origin:Latin
Meaning:Lion
You won't need to roar for everyone to hear and admire your choice of the masculine name Leo. With Latin origins, Leo has been the papal name of 14 popes, including Pope Leo XIV, who was elected to the papacy in 2025. In Latin, leo is the word for "lion," and Leo takes direct inspiration from this word. Stargazers may recognize Leo as the title given to the fifth sign of the zodiac and the lion-shaped constellation located between Cancer and Virgo. Though some may consider it a nickname for Leonard or Leopold, Leo is fully complete in its three-lettered form. The Bump community member ttmccoot is in full agreement with this sentiment, sharing, "I've seen it used on its own plenty of times, and if you're going to call baby Leo, you might as well just name them Leo."
