2020 Longford Senior Football Championship

The 2020 Longford Senior Football Championship was the 104th running of the Longford GAA's premier club Gaelic football tournament for senior graded teams in County Longford, Ireland since the first County Championship was held in 1890 (103 completed since 1890, 1 started but not completed in 1891). The 2020 tournament was originally supposed to consist of 10 teams, but due to the impact of the COVID-19 pandemic on Gaelic games, a total of 12 teams competed this year (due to Rathcline and St Mary's Granard receiving a reprieve from relegation to the 2020 I.F.C.). The championship started with a group stage and then progressed to a knock out stage.

Killoe Young Emmets were the defending champions after they had defeated Longford Slashers in the previous year's final. However the Killoe club received a 48-week ban from the Longford Hearing Committee in August 2020 which would have ruled them out of defending their title in 2020. The ban was appealed to, and deemed illegitimate and quashed by, the GAA's Dispute Resolution Authority (DRA) in September 2020.

This year was Fr. Manning Gaels' return to the top-flight for the first time since the 2017 season after claiming the 2019 Longford I.F.C. title.

Rathcline and St Mary's Granard were supposed to be relegated to the I.F.C. for 2020. However, due to the emergence of the COVID-19 pandemic and the desire to maintain a 12 team S.F.C. for the 2020 Championship, the two clubs were given a reprieve.

Killoe Young Emmets claimed their 13th Senior Football Championship title with victory over Longford Slashers by 0-13 to 1-8 in the delayed 2020 county final played on 29 August 2021. (Note: It was the first time the SFC final was played in a different year to the designated season since the final of 1946 which was delayed and ran into 1947 due to the harvest crisis and various objections that year)

Covid 19 impact
Due to the Covid-19 global pandemic, spectator numbers at group matches were restricted due to requirement for social distancing. By the knock-out stages, spectators were not allowed to attend matches at all, and by mid September spectators were limited to maximum of 200. Most of the 2020 Senior Football Championship was streamed live for the first time to allow supporters who could not attend games to watch the games live via the 'An Longfort TV' online streaming service. The semi-final stages of the Longford Senior Football Championship were postponed following an announcement on 25 September 2020 of two positive Covid-19 cases within the Killoe club. Those two positives were announced as active members of a GAA club, however the source was not GAA related. Public Health Authorities were liaising with the club and players in question and the work involved in contact tracing then commenced. The County board made the decision to postpone the Senior Championship Semi-final games as well as the Intermediate Football Final too. All games were re-arranged for alternate dates in early October 2020. However just before the semi-final games were due to be played, the GAA announced on 5 October that all club activity nationwide would be halted due to Covid-19 spread. The Longford County Board announced later in October 2020 that all unfinished competition which had started in 2020 (including the Senior Football Championship) would conclude in 2021 instead. The semi-finals of the 2020 Longford Senior Football Championship resumed on 21 and 22 August 2021 and the 2020 County Final was played on 29 August 2021.
