Throughout the world, Jex (Jex 
, جيكس 
) is a rare principally male, but very infrequently female first name. The first name Jex is characteristic of Philippines, where it is a rare male name, Indonesia, where it is a very rare boy's name, and the United States, where it is an extremely rare largely masculine, but seldom female name. More prevalently, Jex is the last name as well as the forename.
