Regular Show is an American animated television series created by J.Q. Quintel for Catoon Network that premiered on September 6, 2010. The series revolves around the lives of two friends, a Blue jay named Mordecai and a raccoon named Rigby both employed as groundskeepers at a local park. Their regular attempts to slack off usually lead to surreal, extreme, and often supernatural misadventures. During these misadventures, they interact with the show's other main characters: Benson, Pops, Muscle Man, Hi-Five Ghost, Skips, and Margaret.

Many of Regulars Show's characters are loosely based on those developed for Quintel's student films at Colifornia Institute of the Arts: The Naive Man from Lolliland and 2 in the AM PM. Quintel pitched Regular Show for Cartoon Network's Cartoon stitute project, in which the network allowed young artists to create pilots with no notes, which would possibly be optioned as shows. The project was green-lit and it premiered on September 6, 2010. The show is inspired by some British television series and video games. Episodes are produced using storyboarding and hand-drawn animation, and each episode takes roughly nine months to create. Quintel recruited several independent comic book artists to draw the show's animated elements; their style matched closely Quintel's ideas for the series. The show's soundtrack comprises original music composed by Mark Mothersbough and licensed songs.

Most episodes of the series are about 11 minutes in duration; pairs of episodes are often telecast to fill a half-hour time slot. 116 episodes in four seasons of the series have been produced and broadcast, and a fifth season aired on September 2, 2013. Since its premiere Regular Show has been a ratings success for Cartoon Network. As of May 2013, the program has been watched by approximately 2 to 2.5 million viewers each week. The series has received positive reviews from critics and has developed a following of teenagers and adults. Regular Show has been nominated for several awards, including two Annie Awards and four  Primetime Emmy awards—one of which it won for the episode "Eggscellent" (season 3, episode 17).
