Wacky Races is an American animated television series produced by Hanna-Barbera Productions in association with Heatter-Quigley Productions. It aired on CBS as part of its Saturday-morning schedule from September 14, 1968, to January 4, 1969 and then reruns the next season. The series features 11 different cars racing against each other in various road rallies throughout North America, with all of the drivers hoping to win the title of the "World's Wackiest Racer". The show was inspired by the 1965 comedy film The Great Race. This was the only non-game show produced by Heatter-Quigley; the show was intended as a game show in which children would guess the winner of each race, and those who answered correctly would win prizes, but CBS dropped these elements during development.

The cartoon had many regular characters, with 23 people and animals on the 11 race cars. After its network run on CBS, Wacky Races ran in syndication from 1976 to 1982. Seventeen 20-minute episodes were produced, with each of them featuring two 10-minute segments.

The series spawned numerous spin-offs featuring Dick Dastardly through the years, the most similar in theme being Fender Bender 500 in 1990.

In 2017, the series was remade as a reboot airing on Boomerang. It aired on Cartoon Network on August 13, 2018.
