Meaning & Origin
A female given name from Latin. Clipping of Jillian.
Jill is a girl's and boy's baby name of Latin origin, a short form of Jillian and Gillian — from the Latin Juliana, a feminine form of Julius. The nursery rhyme "Jack and Jill" ensured the name's place in English cultural memory long before it became a popular standalone given name.
Jill ranked in the U.S. top 30 girls' names from the late 1950s through the mid-1970s. Jill Biden's prominence as First Lady gave the name new visibility in the 2020s. It has a clean, unadorned directness — one syllable of complete confidence, requiring nothing more.
