In all the world, อุบลวรรณา (อุบลวรรณา 
, Ubonwanna , Ubolwanna ) is a rare predominantly feminine, but scarcely boy's given name. The forename อุบลวรรณา is characteristic of South-eastern Asia, particularly Thailand, where it is a rare principally female, but very seldom masculine name. Very seldom, อุบลวรรณา is the last name as well as the forename.
