All around the world, Bain (Bain 
, باين 
, Байн 
, among others...) is quite a common unisex forename. The first name Bain is characteristic of Sudan, where it is a rare masculine name, India, where it is a rare gender-neutral name, and Indonesia, where it is a rare principally masculine, but very seldom female name. More prevalently, Bain is the last name as well as the forename.
