The 2020 TLC: Tables, Ladders & Chairs was the 12th annual and final TLC: Tables, Ladders & Chairs 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 December 20, 2020, from the WWE ThunderDome, hosted at Tropicana Field in St. Petersburg, Florida. It was WWE's first PPV to present the ThunderDome from Tropicana Field during the COVID-19 pandemic, following a four-month residency at Orlando's Amway Center. The 2020 event would in turn be the final TLC PPV as the 2021 event was canceled in favor of an event called Day 1.

Seven matches were contested at the event, including one on the Kickoff pre-show. In the main event, Randy Orton defeated The Fiend in a Firefly Inferno match. In the penultimate match, Roman Reigns defeated Kevin Owens in a Tables, Ladders, and Chairs match to retain SmackDown's Universal Championship. In other prominent matches, Raw Women's Champion Asuka and the returning Charlotte Flair defeated Nia Jax and Shayna Baszler to win the WWE Women's Tag Team Championship—subsequently making Flair WWE's fifth Women's Triple Crown Champion and fourth Women's Grand Slam Champion—and in the opening bout, Drew McIntyre defeated AJ Styles and The Miz in a triple threat Tables, Ladders, and Chairs match to retain Raw's WWE Championship; The Miz cashed in his Money in the Bank contract during the scheduled match between McIntyre and Styles, although this cash-in was later nullified as Miz's tag team partner, John Morrison, cashed in the contract on behalf of Miz (only the contract holder can cash in the contract).
