Around the world, Yenisei (Yenisei 
, Эне-Сай 
) is a rare principally feminine, but very infrequently masculine forename. The given name Yenisei is characteristic of Cuba, where it is quite a rare feminine name, Mexico, where it is a rare principally girly, but very seldom masculine name, and Spain, where it is a very rare epicene name. In absolute terms, it is the most numerous in Mexico, Cuba, and the United States. Much less frequently, Yenisei is the last name as well as the forename.
