Dora and the Lost City of Gold is a 2019 American adventure comedy film directed by James Bobin and written by Nicholas Stoller and Matthew Robinson, from a story conceived by Stoller and Tom Wheeler. Based on the Nick Jr. animated television series Dora the Explorer, the film was theatrically released by Paramount Pictures in the United States on August 9, 2019, the same day the final then-unaired episode of Dora the Explorer aired there.

Produced by Paramount Players and Nickelodeon Movies in association with Walden Media, MRC and Burr! Productions, it is a loose live-action adaptation of the aforementioned series and the first such film in the eponymous media franchise as a whole created by Chris Gifford, Valerie Walsh Valdes and Eric Weiner. It stars Isabela Moner, Eugenio Derbez, Michael Peña and Eva Longoria, with Danny Trejo as the voice of Boots. The titular Lost City of Gold is based on the legendary Inca city, Paititi.

A live-action Dora film was announced in 2017, and Moner was cast in the title role in May 2018. Most of the other lead cast members were hired throughout the rest of the year, and filming took place from August to December 2018 in Australia and Peru. John Debney and Germaine Franco were hired to compose the film's score. This film is set after the events of the animated original television series and was also the first film based on a Nick Jr. Channel series.

As a lead–up to the movie, five out of the six unaired episodes of the original series aired on Nick Jr. from July 7 to August 4, 2019. The film received generally positive reviews from critics, who praised Moner's performance and the self-aware humor but was a disappointment at the box office, grossing $120 million worldwide against a budget of $49 million.
