2019 Armagh Senior Football Championship

The 2019 Armagh Senior Football Championship is the 119th edition of Armagh GAA's premier gaelic football tournament for senior clubs in County Armagh, Northern Ireland. The winners represent Armagh in the Ulster Senior Club Football Championship.

The championship begins with sixteen teams competing in four groups of four teams before proceeding to a knock-out format with the overall winners receiving the Gerry Fegan Cup.

Crossmaglen Rangers were the defending champions after they defeated Ballymacnab in the 2018 final. They successfully defended their title when defeating the same opposition in the final on 20 October at the Athletic Grounds to claim their record 45th title.

This was St. Peter's Lurgan's and Culloville Blues' return to the senior grade after they claimed the 2017 I.F.C./I.A.F.L. titles and second in I.A.F.L., respectively.

High Moss Sarsfields and Culloville Blues were relegated to the I.F.C. and I.A.F.L. for 2020 after they finished seventh and eighth in the S.B.F.L. respectively. They will be replaced by the I.F.C. champions Grange St. Colmcille's as well as I.A.F.L. champions Mullaghbawn Cuchulainn's.
