Frozen 2, stylized as Frozen II, is a 2019 American animated musical fantasy film produced by Walt Disney Animation Studios and released by Walt Disney Pictures as the sequel to Frozen (2013). Produced by Peter Del Vecho, the film was directed by Chris Buck and Jennifer Lee from a screenplay by Lee. The directors co-wrote the story with Marc Smith, Kristen Anderson-Lopez, and Robert Lopez. It stars the voices of Kristen Bell, Idina Menzel, Josh Gad, and Jonathan Groff. Set three years after the events of the first film, Frozen 2 follows sisters Anna and Elsa, and their companions Kristoff, Sven, and Olaf as they travel to an enchanted forest to unravel the origin of Elsa's magical power.

Frozen 2 was greenlit in March 2015 after a company debate about whether it would be perceived as inferior to the original. It used more-complex, enhanced animation technology compared to the first film, and was an interdepartmental collaboration. Anderson-Lopez and Lopez returned as the film's songwriters, and Christophe Beck again composed the score. The film was translated into 46 languages and was accompanied by Into the Unknown: Making Frozen 2, a documentary series.

Frozen 2 premiered in Hollywood, Los Angeles, on November 7, 2019, and was released in the United States on November 22. It received generally positive reviews from critics, although it was considered inferior to its predecessor. The film grossed $1.450 billion worldwide, finishing its theatrical run as the third-highest-grossing film of 2019, the tenth-highest-grossing film in history, and the second-highest-grossing animated film of all time. It also held the title of the highest-grossing worldwide opening for an animated film for three years. Frozen 2 received a nomination for Best Original Song at the 92nd Academy Awards, among numerous other accolades. A sequel, Frozen 3, is scheduled to be released in 2027.
