Aqua Teen Hunger Force (also known by Aqua, with various alternative titles), sometimes abbreviated as ATHF or Aqua Teen, is an American adult animated television series created by Dave Willis and Matt Maiellaro for Cartoon Network's late night programming block Adult Swim. It is about the surreal adventures and antics of three anthropomorphic fast food items: Master Shake, Frylock, and Meatwad, who live together as roommates and frequently interact with their human next-door neighbor, Carl Brutananadilewski.

The pilot episode aired as a preview on December 30, 2000. On September 9, 2001, it debuted as an official Adult Swim series. Every episode was directed and written by Willis and Maiellaro, who also provided several voices. Seasons 8–11 were each given a different title, accompanied by different theme music, as a running joke. The series initially concluded on August 30, 2015, after 139 episodes throughout 11 seasons.

Aqua Teen Hunger Force Colon Movie Film for Theaters, a film adaptation of the series, was released in theaters on April 13, 2007, the first adaptation of an Adult Swim series into a feature-length film. A direct-to-video stand alone sequel, Aqua Teen Forever: Plantasm was released on November 8, 2022. A spin-off series of shorts, Aquadonk Side Pieces, was announced the same week, and ran on the network's official YouTube channel from April 18 to April 28, 2022. The series airs in broadcast syndication outside the United States and has been released on various DVD sets and other forms of home media, including video on demand streaming. It was the longest-running Adult Swim series until it was surpassed by Robot Chicken in 2020; a twelfth season consisting of five episodes was announced in January 2023 and premiered on November 26, 2023, making it the longest-running Adult Swim series yet again.
