Jolly Jumper is a horse character in the Franco-Belgian comics series Lucky Luke, created by Belgian artist Morris. Described as "the smartest horse in the west" and able to perform tasks such as chess-playing and tightrope walking, Jolly Jumper accompanies his cowboy in their travels across the Wild West, and delivers frequent quips.
Much like Lucky Luke, the English-language alliterating Jolly Jumper is rarely renamed in translated versions. Although in the Greek version of the series, Jolly Jumper is female and is called "Dolly". In the Turkish version the character is called "Düldül".
