The 2021 season was the Kansas City Chiefs' 52nd season in the National Football League, their 62nd overall and their ninth under head coach Andy Reid. Looking to become the fourth team in NFL history to make three straight Super Bowls, the Chiefs began the season slow, at 3-4 but would finish the regular season 12–5, winning the AFC West division title for the sixth consecutive season. The Chiefs would make, and host, their fourth straight conference championship, but lost to the Cincinnati Bengals in overtime 24–27.
