The 2021 National Conference League was the 36th season of the National Conference League, the top league for British amateur rugby league clubs. Due to the COVID-19 pandemic the tournament had a temporary restructure from its traditional four tiers involving small local round robins across seven areas with the winners and runners-up of each group, as well as a further two teams, entering a playoff system cumulating in one grand final for all four divisions.

Group A

Group E
Gateshead Storm withdrew from the league during the middle of the season.
