All over the world, รัตนิน (Rattanin 
, Ratanin 
, รัตนิน ) is a rare epicene forename. The forename รัตนิน is characteristic of Thailand, where it is a very rare epicene name, and India, where it is a very rare principally girly, but very seldom masculine name. Much less frequently, รัตนิน is the last name as well as the forename.
