The Mayo Senior Hurling Championship is an annual hurling competition contested since 1923 by the top Mayo GAA clubs.
In its current format, the Mayo Senior Championship begins in mid-summer. The 4 participating teams are into one groups and play each other in a round-robin system. The group winners and the runners-up proceed to the final match. The other two teams play the Senior B final. The winner of the Mayo Senior Championship qualifies for the Connacht Intermediate Club Hurling Championship.
Tooreen are the title holders, defeating Ballyhaunis by 1–21 to 0–22 after extra time in the 2024 final.
