Across the world, Дені (Deni 
, Дені 
) is a widespread mostly masculine, but uncommonly female first name. The first name Дені is characteristic of Indonesia, where it is quite a common dominantly boy's, but infrequently female name, Albania, where it is quite a common gender-neutral name, and Croatia, where it is quite a common predominantly male, but very seldom feminine name. In absolute terms, this name is the most popular in Indonesia, India, and Brazil. Very seldom, Дені is the last name as well as the forename.
