The 2019 Ulster Senior Club Football Championship was the 52nd instalment of the annual competition organised by Ulster GAA. It was one of the four provincial competitions of the 2019–20 All-Ireland Senior Club Football Championship. Gaoth Dobhair from Donegal were the 2018 champions following their victory in the final over Monaghan's Scotstown. They didn't get to defend the title after losing the Donegal county final to Naomh Conaill. Down kings Kilcoo were crowned Ulster champions for the first time, defeating Naomh Conaill in the final.
