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 Disney comics and Barks' signature work. Scrooge lives in the city of Duckburg (which is also Donald Duck and Huey, Dewey, and Louie's home city) in the fictional US state of Calisota (a blend of California and Minnesota), whose claimed location is in California in the real-world United States.

Named after the character Ebenezer Scrooge from Charles Dickens' 1843 novella A Christmas Carol, Scrooge is an incredibly rich business magnate and self-proclaimed "adventure-capitalist" whose dominant character traits are his wealth, frugality, and tendency to seek more money through adventure and treasure hunting. Scrooge founded the fictional company McDuck Enterprises and is the maternal uncle of Donald Duck and Della Duck, the maternal great uncle of Huey, Dewey, and Louie, a usual financial backer of Gyro Gearloose, and the world's richest person--all within the context of the fictional Donald Duck universe. He is portrayed as an oil tycoon, businessman, industrialist, and the owner of many factories and the largest mining concerns. Both his "Money Bin" and Scrooge himself are often used as humorous metonyms for great wealth in popular culture around the world.

McDuck was initially characterized as a greedy miser and antihero (similar to Dickens' original Scrooge character), but in later appearances he has often been portrayed as a thrifty hero, adventurer, and explorer. He was originally created by Barks as an antagonist for Donald Duck, first appearing in the 1947 story Christmas on Bear Mountain (Four Color #178). However, McDuck's popularity grew so large that he became a major figure in the Donald Duck universe. In 1952, he was given his own comic book series, called Uncle Scrooge, originally published from 1952-1984, and has had various revivals over the years (as have other Disney comic lines). The most recent revival, by IDW Publishing, ran from 2015-2020.

Scrooge was most famously drawn by his creator Carl Barks, and then later by Don Rosa. Like other Disney franchise characters, Scrooge McDuck's international popularity has resulted in literature that is often translated into other languages. Comics have remained Scrooge's primary medium, although he has also appeared in animated films and television, most extensively in the television series DuckTales (1987–1990), and its reboot (2017–2021), as the main protagonist of both series.
