2019 Kilkenny Senior Football Championship

The 2019 Kilkenny Senior Football Championship was the 126th edition of the Kilkenny GAA's premier club Gaelic football tournament for senior graded teams in County Kilkenny, Ireland. The tournament consisted of 12 clubs with the winner going on to represent Kilkenny in the Leinster Intermediate Club Football Championship. The championship is conducted in a straight knock-out format.

Mullinavat were the defending champions for the second year running after defeating Muckalee in the previous year's final.

This was Tullogher-Rosbercon's return to the senior grade after claiming the 2018 Kilkenny I.F.C. title.

On 11 August 2019, Mullinavat claimed their 4th Kilkenny S.F.C. crown when defeating Railyard by 1-13 to 0-10 after a replay in the final at Nolan Park.

James Stephens were relegated to the 2020 I.F.C. after conceding a walkover to Glenmore in the Relegation Final. This ended their 12 year consecutive streak in the senior ranks since their promotion in 2007.

This tournament was sponsored by JJ Kavanagh and Sons.
