Meaning & origin

Demi entered the U.S. baby name scene in 1964, but its real ascent began in the 1980s. The name's trajectory has been consistently rising since 1985, and it reached its peak popularity in 2020, when it ranked 380. In 2025, roughly 1 in 1,999 newborn girls receive the name Demi. Geographically, Demi has found particular favor in Louisiana, Mississippi, and Illinois. Its gentle sound and modern feel have helped it maintain steady appeal.

Demi is derived from the Greek word 'dēmi-' meaning 'half' or 'small'. It became popular in English-speaking countries as a diminutive of names like Demetria and Demetrius, which are rooted in the goddess Demeter. The name gained widespread use as an independent given name in the late 20th century, partly due to the fame of actress Demi Moore.
