As a popular Finnish girl name, Lumi has the wintery meaning of "snow", however, from its Albanian origins, it is a unisex name, inspired by the name of the northern Albanian Luma tribe. Luma or lumë mean "river" in Albanian, adding another nature connection to this sparky choice.
 
While the name remains rare outside of Finland, Lumi has received more attention in the US in recent years —almost exclusively for girls, though it been given to at least 26 boys since 2018.

Lumi may be a rare <a href="https://nameberry.com/girls-names">girls' name</a> in the USA and England, but it comes in the Top 50 in Finland, where it means snow. Given the popularity of Winter, Holly, Ivy and many other wintery-christmassy names, we think that short and spunky Lumi definitely has potential for greater usage outside its home country as one of the more unusual <a href="https://nameberry.com/list/412/christmas-baby-names">names for Christmas babies</a>. 
 
Lumi can also be considered an Albanian name, derived from the word lumë meaning "river" and inspired by the name of the northern Albanian Luma tribe. In this case, it would be considered a unisex choice and has been used evenly, though very rarely, between the sexes in Albania.
 
Another possibility is that it could come from the Filipino word lumay meaning "gentleness, moderation, manners", making it a sweet and friendly choice but with a grounded meaning. 
 
Given to nearly 90 babies in the US in 2024, use of the name had increased tenfold since 2014.
