Globally, Atchai (อัฐชัย 
, Atchai 
, อะทะไชย ) is a rare primarily masculine, but scarcely girly first name. The given name Atchai is characteristic of South-eastern Asia, particularly Thailand, where it is a rare predominantly male, but very infrequently female name. Very seldom, Atchai is the last name as well as the forename.
