In all the world, Luin (Luin 
, لوين 
) is a rare largely boy's, but seldom feminine first name. The given name Luin is characteristic of Indonesia, where it is a very rare male name, Philippines, where it is a very rare gender-neutral name, and the United States, where it is an extremely rare predominantly masculine, but very seldom female name. Not in comparison with a country's population, the name is most common in Indonesia, India, and Philippines. More frequently, Luin is the last name as well as the forename.
