Around the world, Piyun (Piyun 
) is a very rare largely boy's, but uncommonly girly given name. The forename Piyun is habitual in India, where it is an extremely rare primarily masculine, but scarcely girly name, the United States, where it is an extremely rare unisex name, and China, where it is an extremely rare male name. Much less frequently, Piyun is the last name as well as the forename.
