Across the world, สุทธวรรณ (สุทธวรรณ 
, Sutthawan ) is a rare primarily female, but scarcely masculine first name. The first name สุทธวรรณ is characteristic of South-eastern Asia, particularly Thailand, where it is a rare principally female, but scarcely male name. Much less frequently, สุทธวรรณ is the last name as well as the forename.
