Meaning & origin

Leoni first appeared in U.S. records in 2000, a quiet entry into a diverse landscape of names. It reached its peak rank of 6838 in 2021, but has been declining since 2022. The name fits a pattern of soft, vowel-ending feminine names popular in German and Dutch communities. While it remains rare, its connection to the strong symbol of the lion gives it resonance.

Leoni is a feminine given name of German and Dutch origin, derived from Leon, the Latin word for 'lion'. It is a relatively modern coinage, emerging in the late 20th century as a variant of Leonie or Leona. The name has seen gradual use in German-speaking countries and the Netherlands since the 1990s.
