All over the world, ธิรัตน์ (ธิรัตน์ 
) is a very rare largely boy's, but infrequently feminine first name. The forename ธิรัตน์ is characteristic of South-eastern Asia, particularly Thailand, where it is a very rare largely male, but infrequently girly name. Much less frequently, ธิรัตน์ is the last name as well as the forename.
