Around the World with Willy Fog (Spanish: La vuelta al mundo de Willy Fog) is a Spanish animated television adaptation of the 1873 novel Around the World in Eighty Days by Jules Verne produced by Spanish studio BRB Internacional and Televisión Española, with animation by Japanese studio Nippon Animation, that was first broadcast on TVE1 weekly between 8 January and 15 July 1984.

In the same vein as BRB's Dogtanian and the Three Muskehounds, the characters are anthropomorphisms of various animals as the species depicted are of much greater variety than in that series. The core trio are all felines being pursued by three canine foes. Willy Fog (Phileas Fogg in the original book) is depicted as a lion, while Rigodon (Passepartout) is a cat, and Romy (Aouda) is a panther.

An English dub of the series was directed by Tom Wyner, which featured artists such as Cam Clarke (as Rigodon), Gregory Snegoff (Inspector Dix), Steve Kramer (as Constable Bully) and Mike Reynolds. While the series never achieved popularity in the United States, the English version found fame when it was broadcast on Children's BBC in the United Kingdom. The series was initially screened in 1984 in the UK (and has been repeated many times since) and then on RTÉ in Ireland, while other dubs gained the series fanbases in several other countries. The series was also dubbed into Japanese and aired on Japan's TV Asahi in 1987, where it was titled Anime Around the World in 80 Days (アニメ80日間世界一周, Anime Hachijūnichikan Sekai Isshū).

With all of the international versions, the height of popularity remains in Spain, where a sequel series, Willy Fog 2, was produced in 1993 which has the characters in adaptations of Verne's science fiction novels, Journey to the Center of the Earth and Twenty Thousand Leagues Under the Seas. Furthermore, in 2008, the series spawned a live-action theatrical musical show in celebration of its 25th anniversary.
