2020–21 Northern Premier League
The 2020–21 season was the 53rd season of the Northern Premier League. The league consists of three divisions, the Premier Division at Step 3 of the National League System, and the West and East Divisions at Step 4.
As the previous season was terminated due to the COVID-19 pandemic, with all results removed, there were no changes in the allocations of teams for the Northern Premier League. The planned restructuring of the National League System, including the expansion of the Northern Premier League to include a further division at Step 4, was postponed until 2021–22.
For this season it was announced to member clubs that the League Cup would not take place during the season.
Due to the restrictions on clubs' ability to play matches in the COVID-19 lockdowns, competitions at Steps 3–6 were curtailed on 24 February 2021. The scheduled restructuring of non-league took place at the end of the season, with a new division added to the Northern Premier League at Step 4 for 2021–22. This resulted in 20 extra teams joining the league, either through promotions or reallocations, and some movement of teams currently in the two Division Ones.
