The Monaghan Senior Football Championship is an annual Gaelic football competition contested by Monaghan GAA clubs.

The Monaghan County Board of the Gaelic Athletic Association has organised it since 1888.

Scotstown are the title holders (2024) defeating Clontibret O'Neills in the Final.

The trophy presented to the winners is the Mick Duffy Cup.

The winners can, in turn, go on to play in the All-Ireland Senior Club Football Championship.
