High Quality Content by WIKIPEDIA articles! Ronald McDonald is a clown character used as the primary mascot of the McDonald`s fast-food restaurant chain. In television commercials, the clown inhabits a fantasy world called McDonaldland, and has adventures with his friends Mayor McCheese, the Hamburglar, Grimace, Birdie the Early Bird, and The Fry Kids.
