The 2020–21 Combined Counties Football League season was the 43rd in the history of the Combined Counties Football League, a football competition in England. Teams were divided for the final time into two divisions; the Premier and the First. The constitution was announced on 21 July 2020. After the abandonment of the previous season due to the COVID-19 pandemic, the league's constitution remained largely unchanged, with the planned structural changes being put in place after this season.
