Tangled is a 2010 American animated musical adventure fantasy comedy film produced by Walt Disney Animation Studios and released by Walt Disney Pictures. Loosely based on Rapunzel in the collection of folktales by the Brothers Grimm, it was directed by Nathan Greno and Byron Howard and written by Dan Fogelman. Starring Mandy Moore, Zachary Levi, and Donna Murphy, it tells the story of Rapunzel, a lost young princess with magical long blonde hair who yearns to leave her secluded tower. She accepts the aid of an intruder, the outlaw Flynn Rider, to take her out into the world which she has never seen.

Originally conceived and proposed by Disney animator Glen Keane in 2001, Tangled spent six years in production at a cost that has been estimated at $260 million, which, if accurate, would make it the most expensive animated feature film ever made and one of the most expensive films of all time. The film employed a unique artistic style by blending together features of computer-generated imagery (CGI) and traditional animation while using non-photorealistic rendering to create the impression of a painting. Composer Alan Menken, who had worked on prior Disney animated features, returned to score Tangled, and also wrote the film's songs with lyricist Glenn Slater. Before the film's release, its title was changed from Rapunzel to Tangled, reportedly to market the film gender-neutrally.

Tangled premiered at the El Capitan Theatre in Los Angeles on November 14, 2010, and went into general release on November 24. The film earned $592 million in worldwide box office revenue, $200 million of which was earned in the United States and Canada, making it the eighth-highest-grossing film of 2010. Tangled received positive reviews from critics, who praised the animation, writing, characters, and musical score. The film was nominated for a number of awards, including Best Original Song at the 83rd Academy Awards. It was Richard Kiel's last film role before his death in 2014. The film was released on DVD and Blu-ray on March 29, 2011; a short film, Tangled Ever After, was released later in 2012, and a television series aired from 2017 to 2020. A live-action remake was in development but has been put on hold indefinitely due to the failure of the live-action Snow White film.
