Season 5: Anvil is a season for Halo: The Master Chief Collection, released on January 27, 2021. 343 Industries included previously-cut AKIS and Mariner helmets as part of this update, after they were pushed back from Season 4 due to difficulties encountered during development. Additionally, Season 5 sees the introduction of 12 armor sets from the cancelled game Halo Online into Halo 3.

The season is named after Anvil Station and Anvil Initiative; a space station known for testing the MJOLNIR armors introduced with the update and the organization that runs the station, respectively. The season's logo is the Anvil Initiative's logo: a Human and a Sangheili shaking hands.
