Music of the Marvel Cinematic Universe

The music of the Marvel Cinematic Universe (MCU) covers the soundtracks of the American media franchise and shared universe, which is centered on a series of superhero films produced by Marvel Studios. The films are based on characters that appear in American comic books published by Marvel Comics. The soundtracks include the original scores composed by various composers for the films and television series of the franchise, as well as the songs that are heard in each film.

Ramin Djawadi provided the first MCU music with his original score for Iron Man in 2008. Alan Silvestri was the first composer to work on multiple MCU films, while Brian Tyler was the first composer to reference the work of another MCU composer when he quoted Silvestri's "Captain America March" in his score for Thor: The Dark World (2013) and he composed the previous fanfare for the Marvel Studios production logo from 2013 to 2016. Michael Giacchino has scored five MCU films, the most for any composer in the franchise, and composed the fanfare that has been used for the Marvel Studios production logo since 2016. Original music has also been composed for the Marvel One-Shots short film series and other related MCU projects, and original songs have been created specifically for use in the franchise.

The scores for every MCU film and television series have received album releases, and several compilation albums featuring existing songs used in the films have also been released. Critical response to the MCU's music has been mixed, with focus placed on a lack of memorable themes compared to other large media franchises and on the lack of continuity between works. Some critics have shown more appreciation for the work of more traditional composers like Silvestri, and for Tyler's attempts to establish a consistent tone and thematic continuity for the franchise.
