Worldwide, Hirun (หิรัญ 
, Hirun 
, หิรัณย์ ) is quite a rare principally boy's, but very seldom female forename. The first name Hirun is habitual in Thailand, where it is quite a rare predominantly male, but very infrequently feminine name, Sri Lanka, where it is a rare boy's name, and Saudi Arabia, where it is a very rare masculine name. Not in comparison with a country's population, this name is the most popular in Thailand, India, and Sri Lanka. Very seldom, Hirun is the last name as well as the forename.
