Rocko's Modern Life is an American comedy animated television series created by Joe Murray for Nickelodeon. The series centers on the surreal life of an anthropomorphic Australian immigrant wallaby named Rocko and his friends: the eccentric steer Heffer Wolfe, the neurotic turtle Filburt, and Rocko's faithful dog Spunky. It is set in the fictional town of O-Town. Throughout its run to present day, the series has been controversial for its adult humor, including double entendre, innuendo, and satirical social commentary, helping pave the way for adult animation and earning a cult following, akin to The Ren & Stimpy Show.

Murray created the title character for an unpublished comic book series in the late 1980s, and later reluctantly pitched the series to Nickelodeon, which was looking for edgier cartoonists for its then-new Nicktoons. The network gave the staff a large amount of creative freedom, with the writers targeting both children and adults. The series premiered on September 18, 1993, and ended on November 24, 1996, totaling four seasons and 52 episodes. A special, Rocko's Modern Life: Static Cling, was digitally released on Netflix on August 9, 2019.

The series launched the careers of voice actors Carlos Alazraqui, Tom Kenny, and Mr. Lawrence. After the series ended its run, much of the staff regrouped to work on SpongeBob SquarePants, created by Rocko's creative director Stephen Hillenburg.
