The third season of the animated television series, Aqua Teen Hunger Force originally aired in the United States on Cartoon Network's late night programming block, Adult Swim. Season three started on April 25, 2004 with "Video Ouija" and ended with "Carl" on October 24, 2004, with a total of thirteen episodes. This season continues to focus on the surreal adventures and antics of three anthropomorphic fast food items: Master Shake, Frylock, and Meatwad, who live next door to Carl Brutananadilewski in a suburban neighborhood in New Jersey.

Season three is the only season to feature Spacecataz cold opens, in place of Dr. Weird and Steve. In season three the cold openings featuring Dr. Weird and Steve, were replaced with clips from the failed pilot Spacecataz, a potential spin-off of Aqua Teen Hunger Force. Episodes in season three were written and directed by Dave Willis and Matt Maiellaro, and have TV-14 parental rating. Almost every episode in this season features a special guest appearance, which continues a practice used in past seasons. This season has been made available on DVD, and other forms of home media.
