The 2021 Just World Indoor Bowls Championship took place at Potters Leisure Resort, Hopton-on-Sea, Great Yarmouth, England, from 8–24 January 2021. The event was organised by the World Bowls Tour, televised by the BBC and streamed live on YouTube. The event was played behind closed doors and there was no under-25 competition due to the COVID-19 pandemic. As a consequence of the pandemic there were no overseas players involved. A fairer system was devised in the Open pairs whereby all competitors would face a first round match and there would be no byes.
