The first name Séanna is habitual in Trinidad and Tobago, where it is quite a rare female name, Ireland, where it is a rare feminine name, and the United States, where it is a rare principally female, but very infrequently male name. Not in comparison with a country's population, it is commonest in the United States, the United Kingdom, and Australia. Much less frequently, Séanna is the last name as well as the forename.
