Kildare Senior B Hurling Championship

The Kildare Senior B Hurling Championship (known for sponsorship reasons as the UPMC Kildare Senior B Hurling Championship and abbreviated to the Kildare SBHC) is an annual hurling competition organised by the Kildare County Board of the Gaelic Athletic Association for the second tier hurling teams in County Kildare in Ireland.

In its current format, the Kildare Senior B Championship begins with a group stage. The six participating teams play each other in a round-robin system. This is followed by a knockout phase that culminates with the final match at St Conleth's Park. The winner of the Kildare Senior B Championship qualifies for the subsequent Leinster Intermediate Club Championship.

Leixlip are the title holders after defeating Naas by 1–16 to 2–08 in the 2023 final.

Group stage
Over the course of the six-team group stage, each team plays once against the others in the group, resulting in each team being guaranteed at least five games. Two points are awarded for a win, one for a draw and zero for a loss. The teams are ranked in the group stage table by points gained, then scoring difference and then their head-to-head record. The top four teams from the group stage proceed to the knockout stage.
