Across the world, Rattanasuk (รัตนศักดิ์ 
, Rattanasuk ) is quite a rare predominantly male, but very seldom female first name. The first name Rattanasuk is habitual in South-eastern Asia, particularly Thailand, where it is quite a rare principally masculine, but scarcely girly name. Much less frequently, Rattanasuk is the last name as well as the forename.
