Chicken Little is a 2005 American animated science fiction comedy film produced by Walt Disney Feature Animation and released by Walt Disney Pictures. It was directed by Mark Dindal from a screenplay by Steve Bencich, Ron J. Friedman, and Ron Anderson, based on a story by Dindal and Mark Kennedy, loosely inspired on the European folk tale "Henny Penny", known in the United States as "Chicken Little". In this version, the title character is ridiculed by his town for causing a panic, thinking that the sky was "falling". A year later he attempts to fix his reputation, followed by an unexpected truth regarding his past being revealed. The film is dedicated to Disney artist and writer Joe Grant, who died before the film's release. This also marked the final film appearance of Don Knotts during his lifetime, as his next and final film, Air Buddies (another Disney-produced film that was released just over a year later), would be released posthumously.

Chicken Little was animated in-house at Walt Disney Feature Animation's main headquarters in Burbank, California. It is Disney Animation's first fully computer-animated feature film, as Dinosaur (2000) was a combination of live-action and computer animation which in turn was provided by Disney's The Secret Lab.

Chicken Little was Disney's second adaptation of the fable after an anti-Nazi propaganda cartoon made during World War II, serving as a loose remake to the cartoon. The film is also the last Disney animated film produced under the name Walt Disney Feature Animation before the studio was renamed Walt Disney Animation Studios. Chicken Little premiered at the El Capitan Theatre in Hollywood, Los Angeles on October 30, 2005, and had its wide release on November 4, in Disney Digital 3-D (the first film to be released in this format) and 2D. It received mixed reviews from critics and grossed $314 million worldwide, making it the second-highest-grossing animated film of 2005 (behind Madagascar).
