Spirit Untamed is a 2021 American animated adventure film produced by DreamWorks Animation and distributed by Universal Pictures. The film was directed by Elaine Bogan (in her feature directorial debut) and co-directed by Ennio Torresan Jr., from a screenplay written by Aury Wallington and Kristin Hahn. The second theatrical release of the Spirit franchise, it is a soft reboot of the traditionally animated Spirit: Stallion of the Cimarron (2002) and is based on characters from the Netflix spin-off television series Spirit Riding Free, developed by Wallington.

Featuring the voices of Isabela Merced, Jake Gyllenhaal, Marsai Martin, Mckenna Grace, Julianne Moore, Walton Goggins, and Andre Braugher in his only animated feature film, the film follows a young girl named Fortuna "Lucky" Prescott who moves to the small rural community of Miradero, where she meets the titular wild kiger mustang. As the son of Spirit and Rain from Spirit: Stallion of the Cimarron, she names the horse "Spirit" after his father, and Lucky immediately begins to bond with him. The film was announced to be in development in October 2019, and production was done remotely during the COVID-19 pandemic. The film was dedicated to the memory of Kelly Asbury, the co-director of the original Spirit film, who died on June 26, 2020.

Spirit Untamed was theatrically released in the United States on June 4, 2021. The film received mixed reviews from critics who deemed the film inferior to the original and unnecessary, though its animation and humor was praised. The film grossed over $42 million worldwide against a budget of $30 million, making it both DreamWorks Animation's cheapest film and its lowest-grossing film to date.
