Worldwide, オア (Orr , オア ) is a rare largely boy's, but seldom female first name. The first name オア is characteristic of Israel, where it is a rare epicene name, the United States, where it is a very rare predominantly boy's, but scarcely feminine name, and the United Kingdom, where it is a very rare gender-neutral name. Not in comparison with a country's population, it most frequently occurs in the United States, China, and Israel. Much more prevalently, オア is the last name as well as the forename.
オア is also a name for the fictitious and mythical characters: Orr , the fictional character in the novel Catch-22.
