The 2019–20 Premiership Rugby Cup was the 48th season of England's national rugby union cup competition and the second under the new Premiership Rugby Cup format following the disbanding of the Anglo-Welsh Cup at the end of the 2017–18 season due to the withdrawal of the Welsh Pro14 regions. Although there were no stipulations on player selection, the cup was seen by many clubs as a development competition, and games took place during the 2019 Rugby World Cup and during the Six Nations.
