Throughout the world, Wibul (วิบูลย์ 
, Wibul 
) is quite a rare principally male, but scarcely feminine first name. The forename Wibul is habitual in South-eastern Asia, particularly Thailand, where it is quite a rare predominantly masculine, but very infrequently female name. Much less frequently, Wibul is the last name as well as the forename.
