The 2020-2021 WWE Hall of Fame was a professional wrestling event produced by WWE that featured the induction of the 21st and 22nd classes to the WWE Hall of Fame. Due to the COVID-19 pandemic, the 2020 Hall of Fame ceremony did not occur—as a result, the originally announced Class of 2020 was inducted alongside the Class of 2021 at the 2021 induction ceremony. The event was taped on March 30 and April 1, 2021, at the WWE ThunderDome, hosted at Tropicana Field in St. Petersburg, Florida, and aired on April 6 on Peacock in the United States and the WWE Network internationally. Jerry Lawler served as the host for the Class of 2020 portion of the show while Corey Graves and Kayla Braxton were the hosts for the Class of 2021 portion.
