In the world, จอมชัย (Jomchai 
, จอมชัย ) is a very rare principally masculine, but very seldom female first name. The first name จอมชัย is habitual in South-eastern Asia, particularly Thailand, where it is a very rare principally boy's, but very seldom feminine name. Much less frequently, จอมชัย is the last name as well as the forename.
