The 2019 American adventure comedy film Dora and the Lost City of Gold was written by Nicholas Stoller, Tom Wheeler, and Matthew Robinson and helmed by James Bobin. The movie, which is based on the Nick Jr. animated television series Dora the Explorer, was released in theaters in the US on August 9, 2019, the day that the last episode of the show, which had not yet aired, 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. 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 and grossed $120 million worldwide against a budget of $49 million.
