The Cork Junior B Football Championship (known for sponsorship reasons as the Bon Secours Cork Junior B Football Championship and abbreviated to the Cork JBFC) is an annual Gaelic football competition organised by the Cork County Board of the Gaelic Athletic Association and contested by junior clubs in the county of Cork in Ireland. It is the seventh tier overall in the entire Cork football championship system.

The Cork Junior B Championship was introduced as a knockout tournament in 1984. In its current format, the championship is completed over the course of ten weeks. Unlike the Cork Junior A Football Championship, it is a countywide competition not limited to divisional champions. The championship includes a round robin followed by a knockout stage, which culminates with the final match at Páirc Uí Rinn.

The competition has been won by 27 teams, eight of which have won it more than once. Argideen Rangers are the most successful team in the competition's history, having won it four times. St Oliver Plunketts are the title holders after defeating Ballyphehane by 1–10 to 1–09 in the 2023 final.^[1]

The 12 teams are divided into two groups of four and two groups of three. Over the course of the group stage, each team plays once against the others in the group. 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 two teams in each group qualify for the knockout stage.

Quarter-finals: The eight qualifying teams from the group stage contest this round. The four winners from these four games advance to the semi-finals.

Semi-finals: The four quarter-final winners contest this round. The two winners from these four games advance to the semi-finals.

Final: The two semi-final winners contest the final. The winning team are declared champions.
