How to Train Your Dragon is an upcoming American fantasy film written, co-produced, and directed by Dean DeBlois. It is a live-action remake of DreamWorks Animation's 2010 animated film How to Train Your Dragon, which itself was loosely based on the 2003 novel How to Train Your Dragon by Cressida Cowell. 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. This is the first live action production from DreamWorks Animation.

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 having previously worked on the animated film trilogy, while John Powell, who also worked on the original 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, the film is set to be released theatrically by Universal Pictures in the United States on June 13, 2025.
