The 2020–21 RFU Championship, also known as the 2020–21 Greene King IPA Championship for sponsorship reasons, was the twelfth season of the RFU Championship, the professional second tier of rugby union in England. It featured ten English teams and one from Jersey. The competition was sponsored by Greene King for the eighth successive season. Due to the COVID-19 pandemic in the United Kingdom, this season featured a truncated timeframe of just 16 weeks with a later start and fewer rounds.
