"Just who might be called an Olympian is not entirely clear. For example, Dowden, p. 43, describes Heracles, Hebe, the Muses, and the Graces as Olympians, and on p. 45, lists Iris, Dione, and Eileithyia among the Homeric Olympians, while Hansen, p. 250, describes Heracles, Hebe, the Horae, and Ganymede as notable residents of Olympus, but says they "are not ordinarily classified as Olympians"."
