All over the world, Prachak (ประจักษ์ 
, ประจักร์ , ประจักร ) is a common principally boy's, but very seldom feminine first name. The forename Prachak is habitual in Thailand, where it is quite a common principally masculine, but very infrequently girly name, and India, where it is an extremely rare unisex name. Very seldom, Prachak is the last name as well as the forename.
