All over the world, พิบูลย์ชัย (พิบูลย์ชัย 
, Piboonchai , Phiboonchai ) is a very rare predominantly male, but scarcely female first name. The forename พิบูลย์ชัย is habitual in South-eastern Asia, particularly Thailand, where it is a very rare predominantly boy's, but very infrequently girly name. Very seldom, พิบูลย์ชัย is the last name as well as the forename.
