Frozen is a 2013 American animated musical fantasy film produced by Walt Disney Animation Studios and released by Walt Disney Pictures. Inspired by Hans Christian Andersen's 1844 fairy tale "The Snow Queen", it was directed by Chris Buck and Jennifer Lee (in her feature directorial debut) and produced by Peter Del Vecho, from a screenplay by Lee, who also conceived the film's story with Buck and Shane Morris. The film stars the voices of Kristen Bell, Idina Menzel, Jonathan Groff, Josh Gad, and Santino Fontana. It follows Anna, the princess of Arendelle, who sets off on a journey with the iceman Kristoff, his reindeer Sven, and the snowman Olaf, to find her estranged sister Elsa after she accidentally traps their kingdom in eternal winter with her icy powers.

Frozen underwent several story treatments before it was commissioned in 2011. Christophe Beck was hired to compose the film's orchestral score, and Robert Lopez and Kristen Anderson-Lopez wrote the songs.

After its world premiere at the El Capitan Theatre in Los Angeles on November 19, 2013, Frozen had its general theatrical release on November 27. It was praised for its visuals, screenplay, themes, music, and voice acting, and some critics consider it Disney's best animated film since the studio's Renaissance era. The film grossed over $1.280 billion worldwide, becoming the highest-grossing animated film until the remake of The Lion King overtook this position in August 2019. It finished its theatrical run as the highest-grossing film of 2013 and the fifth-highest-grossing film of all time. The film's songs, characters, story, and appeal to a general audience led to it being dubbed a pop culture phenomenon.

The film's popularity spawned a franchise which includes an animated short in 2015, a 2017 animated featurette and two feature-length sequels—Frozen 2 (2019) and the upcoming Frozen 3 (2027).

Among its accolades, it won Academy Awards for Best Animated Feature and Best Original Song, the Golden Globe Award for Best Animated Feature Film, the BAFTA Award for Best Animated Film, and two Grammy Awards.
