Throughout the world, วิทยาศักดิ์ (วิทยาศักดิ์ 
, Vittayasak , Wityasak) is a very rare principally male, but scarcely feminine forename. The given name วิทยาศักดิ์ is characteristic of South-eastern Asia, particularly Thailand, where it is a very rare primarily male, but scarcely female name. Much less frequently, วิทยาศักดิ์ is the last name as well as the forename.
