Superjail! is an American adult animated television series created by Christy Karacas, Stephen Warbrick and Ben Gruber for Cartoon Network's late night programming block, Adult Swim. It follows the events that take place in an unusual prison. The pilot episode aired on May 13, 2007, and its first season began on September 28, 2008.

Superjail! is characterized by its psychedelic shifts in setting and plot and extreme graphic violence, which give the series a TV-MA-V rating (for graphic violence, including scenes of bloodshed, dismemberment, torture, and extreme cruelty). These elements are depicted through highly elaborate animated sequences, which have been described as "Baroque and complicated and hard to take in at a single viewing".
