Throughout the world, Onnisa (Onnisa 
, อรณิสา ) is a very rare principally girly, but very seldom boy's forename. The given name Onnisa is habitual in Thailand, where it is a very rare primarily female, but scarcely masculine name, and India, where it is an extremely rare girly name. Much less frequently, Onnisa is the last name as well as the forename.
