Globally, Aosan (اوسان 
, Aosan 
) is a rare primarily male, but scarcely female forename. The forename Aosan is characteristic of Yemen, where it is a rare predominantly masculine, but very infrequently female name, Saudi Arabia, where it is a rare masculine name, and India, where it is an extremely rare primarily male, but scarcely female name. Much less frequently, Aosan is the last name as well as the forename.
