The 2020–21 Gibraltar National League season is the second season of the new Gibraltar National League in Gibraltar, and the 122nd season of football on the territory overall. There are no reigning champions this season, as the previous season was declared abandoned as a result of the COVID-19 pandemic. The league is due to kick off on 16 October 2020. Instead of qualifying for the 2021–22 UEFA Europa League, teams placed 2nd, 3rd and the 2021 Rock Cup winners will qualify for the inaugural UEFA Europa Conference League.

Lincoln Red Imps Football Club is a professional association football club from Gibraltar. They play in the Gibraltar National League, and share Victoria Stadium with all other clubs in the territory. They are the country's record champion with 27 league titles, including fourteen consecutive titles between 2003 and 2016, and in 2014 were the first team to represent Gibraltar in the UEFA Champions League's qualifying stage. In August 2021, Lincoln became the first club from Gibraltar to ever reach the group stages of a European club competition after defeating the Latvian champions Riga FC in the play-off round of the UEFA Europa Conference League.
