Established in 1895 as a championship for the second teams of clubs playing in the
Cork Senior Championship, the junior championship was initially played on a countywide basis. With the creation of the
Cork Intermediate Championship in 1909, victorious clubs in the junior grade were gained promotion to the intermediate grade. As more and more clubs were founded, the decision was taken in 1926 to organise the junior championship on a divisional basis. Each of the eight divisions provided their championship-winning team to represent their division in the county championship. After the intermediate grade was disbanded in 1939, the winners of the Cork Junior Championship gained promotion to the Cork Senior Championship. This system of promotion and relegation lasted until 1964 when the intermediate grade was reintroduced. In 2017 the eight divisional runners-up were also allowed to field teams in the junior championship. ==Sponsorship==
