Throughout the world, Alsan (Alsan 
, السان 
) is a rare principally masculine, but very seldom female first name. The first name Alsan is characteristic of Sudan, where it is a rare masculine name, Philippines, where it is a rare principally male, but very seldom feminine name, and Nigeria, where it is a very rare primarily masculine, but scarcely female name. Not in comparison with a country's population, it is commonest in Nigeria, Philippines, and India. More prevalently, Alsan is the last name as well as the forename.
