The Clan McDuck is a fictional Scottish clan of cartoon ducks from which Disney character Scrooge McDuck is descended. Within the Donald Duck universe, the clan is related to the American Duck family through the marriage of Hortense McDuck and Quackmore Duck, Donald and Della Duck's parents, giving both of them partial Scottish ancestry.

Scrooge McDuck is a cartoon character created in 1947 for The Walt Disney Company by Carl Barks. Appearing in Disney comics, Scrooge is a Scottish-born American anthropomorphic Pekin duck. Like his nephew, Donald Duck, he has a yellow-orange bill, legs, and feet. He typically wears a red or blue frock coat, top hat, pince-nez glasses, and spats varying in color. He is portrayed in animation as speaking with a Scottish accent. Originally intended to be used only once, Scrooge became one of the most popular characters in the Disney comics world, as well as Barks' signature work. Scrooge is an extremely rich duck who lives in the fictional city of Duckburg in the fictional U.S. state of Calisota, whose claimed location is in California in the real-world United States.
