All over the world, Саина (Saina 
, Sayna 
, Саина 
) is a common predominantly feminine, but very infrequently masculine forename. The forename Саина is habitual in India, where it is quite a rare predominantly girly, but very infrequently masculine name, Saudi Arabia, where it is a rare epicene name, and Qatar, where it is a rare female name. Not in comparison with a country's population, the name is most common in India, Indonesia, and the Democratic Republic of the Congo. Very seldom, Саина is the last name as well as the forename.
