Here is every superhero movie that will be released in 2021. Superhero movies have become the dominant genre of blockbuster entertainment in recent years. The Marvel Cinematic Universe is the biggest movie franchise of all-time and saw Avengers: Endgame become the highest-grossing movie ever in 2019. Their output is increasing in 2021 to include four movies and six Disney+ shows. The MCU's ongoing popularity has led Sony to restart its efforts to build its own Marvel shared universe. Meanwhile, the DC Extended Universe is continuing to move forward with plans to release as many as six movies per year between theaters and on HBO Max.

With so much superhero content on the way, Hollywood studios stake out release dates for the highly-anticipated titles years in advance. However, that doesn't mean that everything always goes according to plans. 2021 was at one time going to include many films that no longer are coming out this year. Matt Reeves' The Batman starring Robert Pattinson was pushed to 2022 following extensive production delays from COVID-19. The same is true for Marvel Studios' Doctor Strange in the Multiverse of Madness. Dwayne Johnson's Black Adam was scheduled for a December 2021 release too, but it lost that release date in late 2020.

These delays to 2021's movies were also partially done so that studios could find a home for the 2020 superhero films they couldn't release. COVID-19 shut down theaters for months and forced every major Hollywood studio to reshuffle their slates. But, there are also some titles coming out in 2021 that most never thought would be released. With all of that in mind, here are the superhero movies coming out in 2021.
