Throughout the world, มนัญชญา (มนัญชญา 
, Mnanchaya , Mananshaya ) is a rare largely female, but uncommonly boy's first name. The forename มนัญชญา is characteristic of South-eastern Asia, particularly Thailand, where it is a rare dominantly female, but uncommonly masculine name. Very seldom, มนัญชญา is the last name as well as the forename.
