How to Train Your Dragon is a 2025 American fantasy film produced, written, and directed by Dean DeBlois. It is a live-action remake of DreamWorks Animation's 2010 animated film, itself loosely based on the first novel in Cressida Cowell's book series. The film stars Mason Thames, Nico Parker, Nick Frost, Julian Dennison, Gabriel Howell, Bronwyn James, Harry Trevaldwyn, Ruth Codd, Peter Serafinowicz, and Murray McArthur, with Gerard Butler reprising his role as Stoick the Vast from the animated films. It is the first live-action production from DreamWorks Animation, as well as its first production to be a remake.

Plans for a live-action remake of How to Train Your Dragon were announced in February 2023, with DeBlois returning to write, direct, and produce after previously spearheading the animated film trilogy. John Powell, who also worked on the trilogy, additionally returned to compose the score for the film. Thames and Parker joined the cast by May 2023, with additional casting revealed in January 2024. Filming began later that month in Belfast, Northern Ireland and wrapped in May.

Produced by DreamWorks Animation and Marc Platt Productions, How to Train Your Dragon premiered at CinemaCon on April 2, 2025, and is set to be released theatrically by Universal Pictures in the United States on June 13, 2025. A sequel is scheduled to be released on June 11, 2027.
