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.

Lucky Luke is a Western bande dessinée series created by Belgian cartoonist Morris in 1946. Morris wrote and drew the series single-handedly until 1955, after which he started collaborating with French writer René Goscinny. Their partnership lasted until Goscinny's death in 1977. Afterwards, Morris used several other writers until his own death in 2001. Since Morris's death, French artist Achdé has drawn the series, scripted by several successive writers.
