A bobblehead doll, also known as a bobbing head doll, nodder, or wobbler, is a type of collectible toy. Its head is often oversized compared to its body. Instead of a solid connection, its head is connected to the body by a spring or hook in such a way that a light tap will cause the head to bobble, hence the name.

Although bobblehead dolls have been made with a wide variety of figures such as breakfast cereal mascot Count Chocula, beat generation author Jack Kerouac, and Nobel Prize–winning geneticist James D. Watson, the figure is most associated with athletes, especially baseball players.
