The 2020–21 Rugby Pro D2 is the second-level French rugby union club competition, behind the Top 14, for the 2020–21 season. It will run alongside the 2020–21 Top 14 competition; both competitions are operated by the Ligue Nationale de Rugby (LNR). After play was suspended following the 23rd Matchday of the 2019–20 season due to the COVID-19 pandemic in France, the season was officially cancelled without any winner or promotion/relegation on 6 May.
