The 2020 Hell in a Cell was the 12th annual Hell in a Cell professional wrestling pay-per-view (PPV) and livestreaming event produced by WWE. It was held for wrestlers from the promotion's Raw and SmackDown brand divisions. The event took place on October 25, 2020, from the WWE ThunderDome, hosted at the Amway Center in Orlando, Florida. This was the final Hell in a Cell held during the month of October, as the 2021 event moved the event series up to June.

Seven matches were contested at the event, including one on the Kickoff pre-show. Three Hell in a Cell matches were contested at the event, two were for the SmackDown brand, while the other was for Raw. In the main event, Randy Orton defeated Drew McIntyre in a Hell in a Cell match to win the WWE Championship for a tenth time, thus tying with Triple H for the second-most world title reigns overall at 14. For the other Hell in a Cell matches, Roman Reigns defeated Jey Uso to retain the Universal Championship in the opening bout, which was also the first time an "I Quit" match was contested inside the structure, while Sasha Banks defeated Bayley to win the SmackDown Women's Championship, thus ending Bayley's record-setting title reign at 380 days. This made Banks the third WWE Women's Grand Slam Champion, as well as the fourth WWE Women's Triple Crown Winner.
