The Official Avengers: Doomsday Trailer Is Finally Here

Originally published on July 20, 2026. This article covers the release of the official Avengers: Doomsday trailer from Marvel Studios.

Marvel Studios initially released four separate teaser trailers for Avengers: Doomsday. Each short trailer focused on a single character or a set of main characters. These teasers did not reveal much about the film’s plot. Instead, they introduced various narratives for our favorite heroes. Most saw the Avengers and their allies (including the X-Men) in dire straits, preparing for or fighting against their seemingly inevitable doom.

Ahead of the film’s widely anticipated release, fans have been expecting a main trailer. Now it’s finally here, complete with a first look at Doctor Doom! Watch the official Avengers: Doomsday trailer here or on Marvel Studios’ official YouTube channel. Then, join us below to learn more about the latest MCU movie — like the release date, cast members, and more.

Avengers: Doomsday Release Date

• Avengers: Doomsday Release Date: December 18, 2026

In the trailer, we see Thor leading the charge, assembling heroes and even former villains from across the Multiverse. Wakandans meet the Fantastic Four, New Avengers cross paths with the X-Men, and even Steve Rogers returns. This time it’s not just the universe or the Multiverse. It’s reality itself.

And you’ll only have to wait a few more months! Avengers: Doomsday releases exclusively in theaters on December 18, 2026. We expect the movie to hit the Disney+ streaming platform a few months after the theatrical release, as is the general pattern with MCU drops.

We also have the live countdown, or the DOOMSDAY CLOCK, on Marvel’s YouTube.
