2020 Galway Senior Football Championship

The 2020 Galway Senior Football Championship is the 125th edition of Galway GAA's premier Gaelic football tournament for senior graded clubs in County Galway, Ireland. The winners receive the Frank Fox Cup but will not represent Galway in the Connacht Senior Club Football Championship, which was cancelled for 2020 due to the impact of the COVID-19 pandemic on Gaelic games.
Eighteen teams compete in the competition. This year's format was originally planned to mirror last year's format with the draw being carried out in February 2020. However due to the emergence of the COVID-19 pandemic, the format was altered to reduce the number of matches to be played. A new draw was made on 3 July 2020 to compensate for these changes.
Corofin were the defending champions for the sixth consecutive year after they defeated Tuam Stars after a replay in the 2019 final. The holders were beaten by Mountbellew/Moylough in the Semi Final that ended a remarkable 49 game unbeaten run in the championship dating back to 2012.
This was All Ireland I.C.F.C. champions Oughterard's return the senior grade for the first time in 17 seasons after they claimed to 2019 I.F.C. title. They were promoted along with the I.F.C. finalists Michael Breathnach's, who return to the Senior grade after their relegation in 2017.
