Meaning & origin

Demii is a modern invented name that first appeared on U.S. birth records in 2010. It has been rising in use since 2015 and reached its peak rank in 2022. The name is extremely rare, with an estimated 1 in every 229,610 baby girls receiving it in 2025. Its spelling with a double 'i' aligns with contemporary naming trends that favor creative variations. Despite its rarity, Demii has not been concentrated in any specific U.S. state, indicating a broad but sparse distribution. The name likely draws from the more established Demi, offering a distinctive twist for parents seeking something unique.

Demii is a modern coinage, first recorded in the United States in 2010. It appears to be a respelling or stylized variant of Demi, itself a short form of Demetria or a nickname from names like Demetrius. The doubled 'i' ending follows a fashionable pattern seen in other contemporary invented names, such as 'Lexii' or 'Mackenzii'.
