2018 Tipperary Senior Football Championship

The 2018 Tipperary Senior Football Championship (sponsored by Tipperary Water) was the 128th edition of the Tipperary GAA's premier club Gaelic football tournament for senior graded teams in County Tipperary, Ireland. The tournament consisted of 16 clubs with the winner going on to represent Tipperary in the Munster Senior Club Football Championship. The championship began with a Group stage before proceeding to a knock-out format. The winning Club received the O'Dwyer Cup.

Clonmel Commercials were the defending champions, however the defence of their title came undone at the semi-final stage when losing to eventual champions Moyle Rovers.

This was Kiladangan's debut in the senior grade after claiming the 2017 Tipperary I.F.C. title.

On 28 October 2018, Moyle Rovers claimed their 9th Tipperary S.F.C. crown when defeating Ardfinnan by 1-15 to 1-7 in the final at Semple Stadium. This was their first triumph since 2009.

Drom-Inch GAA were relegated to the 2019 I.F.C. after losing their Relegation Final to ???. This ended their four year tenure in the senior ranks since their promotion in 2014.

The draw for the group stage was made on 28 January 2019.
