Marvel Cinematic Universe timeline

The fictional timeline of the Marvel Cinematic Universe (MCU) media franchise and shared universe is the continuity of events for several feature films, television series, television specials, short films, and the I Am Groot shorts, which are produced by Marvel Studios, as well as a group of Netflix series produced by Marvel Television. Within the multiverse of the MCU, the main setting for most media is the Earth-616 universe which is also known as the "Sacred Timeline". Media set outside of the multiverse or in alternate universes are noted.

Most of the films in the franchise's Phase One and Phase Two follow a similar timeline order to their releases, but Phase Three saw many of the films overlapping with each other. The Phase Three film Avengers: Endgame (2019) includes a five-year time jump, with many subsequent releases in Phase Four and Phase Five taking place after Endgame. The television series Loki (2021–2023) and What If...? (2021–2024) were the first properties to occur outside of the main timeline and explore alternative timelines and universes.

Marvel Studios has made several attempts to codify the MCU's events and address perceived continuity errors. An official timeline book, covering projects from the first four phases, was released in 2023. The book does not feature projects produced by other companies, such as Marvel Television's series which are loosely connected to the films, but it notes that these projects are part of the larger Marvel canon. In early 2024, Marvel Studios integrated Marvel Television's Netflix series into their Disney+ timeline. As of the Phase Five television series Daredevil: Born Again (2025) and film Thunderbolts* (2025), the "present day" in the MCU is 2027.
