The 2020–21 European Rugby Champions Cup pool stage is the first stage of the 26th season of European club rugby union, and the seventh under the European Rugby Champions Cup format. Due to the COVID-19 pandemic delaying the end of the previous tournament, twenty-four clubs from the three major European domestic and regional leagues would compete in the Champions Cup in a one-year exceptional basis. EPCR chief Vincent Gaillard confirmed the 24-team tournament in August 2020. The competition was suspended on 11 January 2021.
