Across the world, วิยะวรรณ (วิยะวรรณ 
, Viyawan ) is a very rare mostly feminine, but uncommonly masculine first name. The forename วิยะวรรณ is characteristic of South-eastern Asia, particularly Thailand, where it is a very rare dominantly girly, but uncommonly boy's name. Much less frequently, วิยะวรรณ is the last name as well as the forename.
