Dora and the Fantastical Creatures is a 2023 American animated short film based on the animated television series Dora the Explorer created by Chris Gifford, Valerie Walsh Valdes, and Eric Weiner. Produced by Nickelodeon Animation Studio, the film was directed by William Mata from a screenplay by Alejandro Bien-Willner and a story by Bien-Willner and Sean Gill. It stars the voices of Diana Zermeño, Asher Spence, Marc Weiner, Kate del Castillo, Anairis Quiñones, and Danny Burstein. The film sees Dora and Boots embark on an adventure to the land of the alebrijes and save their Copal Tree Celebration.

The magical world the film takes place in is inspired by Mexican folk art and alebrijes. As alebrijes are made of wood, the production team aimed to reflect that in the animation and make it look handmade. The film served as an early promotion for the reboot series Dora and premiered in theaters on September 29, 2023, along with PAW Patrol: The Mighty Movie.
