Worldwide, Wansak (วรรณศักดิ์ 
, Wansak 
, วันสัก ) is a rare principally male, but scarcely girly forename. The first name Wansak is habitual in South-eastern Asia, particularly Thailand, where it is a rare primarily male, but very seldom feminine name. Much less frequently, Wansak is the last name as well as the forename.
