Around the world, สุทธินาถ (สุทธินาถ 
, Suttinat 
, Suthanat ) is a very rare dominantly female, but infrequently masculine forename. The given name สุทธินาถ is habitual in South-eastern Asia, particularly Thailand, where it is a very rare largely girly, but infrequently boy's name. Very seldom, สุทธินาถ is the last name as well as the forename.
