) is a rare dominantly girly, but uncommonly male given name. The forename Adaina is characteristic of Nicaragua, where it is a rare female name, Philippines, where it is a very rare feminine name, and Mexico. Not in comparison with a country's population, it is commonest in Philippines, the United States, and India. Very seldom, Adaina is the last name as well as the forename.
