All around the world, สิทธิยาภรณ์ (สิทธิยาภรณ์ 
) is a very rare mostly boy's, but infrequently girly given name. The forename สิทธิยาภรณ์ is characteristic of South-eastern Asia, particularly Thailand, where it is a very rare largely male, but seldom feminine name. Very seldom, สิทธิยาภรณ์ is the last name as well as the forename.
