All over the world, ปิยะวัน (ปิยะวัน 
, Peeyavan ) is a very rare dominantly girly, but uncommonly boy's given name. The first name ปิยะวัน is characteristic of South-eastern Asia, particularly Thailand, where it is a rare dominantly female, but infrequently masculine name. Very seldom, ปิยะวัน is the last name as well as the forename.
