Across the world, อรุณสุดา (อรุณสุดา 
, Aonsud ) is a very rare principally girly, but scarcely boy's first name. The forename อรุณสุดา is characteristic of South-eastern Asia, particularly Thailand, where it is a very rare principally female, but very infrequently masculine name. Likewise, อรุณสุดา is the last name as well as the forename.
