The first name האף is habitual in Nigeria, where it is a very rare epicene name, South Africa, where it is a very rare masculine name, and the United States, where it is an extremely rare predominantly male, but scarcely girly name. Not in comparison with a country's population, the name is most common in Nigeria, China, and South Africa. Much more prevalently, האף is the last name as well as the forename.
