The 2021 AFL Grand Final was an Australian rules football match contested between Melbourne and the Western Bulldogs at Optus Stadium in Perth, Western Australia, on Saturday 25 September 2021. It was the 126th annual grand final of the Australian Football League (AFL), staged to determine the premiers of the 2021 AFL season. As the top-placed side on the ladder at the end of the 2021 home-and-away season, Melbourne finished minor premiers, whereas the Western Bulldogs faded in the final four home-and-away games to finish 5th, thus needing to win all of their finals games to qualify for the grand final.
