2020 Antrim Senior Football Championship

The 2020 Antrim Senior Football Championship is the 118th edition of the Antrim GAA's premier club Gaelic football tournament for senior graded teams in County Antrim, Northern Ireland. The tournament consists of 13 teams, with the winner going on to represent Antrim in the Ulster Senior Club Football Championship. The championship changed its format this year.
