The All-Ireland Senior B Hurling Championship was a hurling competition held annually between 1974 and 2004 and organised by the Gaelic Athletic Association (GAA). It was contested by those county teams which were knocked out in the first round of the All-Ireland Senior Hurling Championship, with the winner awarded the championship.
The series of games began every year immediately after the completion of the National Hurling League, with the All-Ireland final being played in June or July, initially in Croke Park, Dublin, but later in provincial venues around the country and in Britain. The championship was abolished in 2004, with the teams involved later playing in, first, the Christy Ring Cup, and since 2018, the Joe McDonagh Cup.
The title was won by 11 different teams, 6 of which won the title more than once. The all-time record-holder is London, which won the competition 5 times. The history of the championship was bookended by victories for Kildare, winner of the first title in 1974 and the last in 2004.
