Across the world, Tiean (เทียน 
, 铁安 
, Tiean 
) is quite a rare gender-neutral given name. The first name Tiean is characteristic of Thailand, where it is quite a rare epicene name, and China, where it is a very rare principally boy's, but very seldom feminine name. Much less frequently, Tiean is the last name as well as the forename.
