The All-Ireland Senior B Hurling Championship was a second tier Hurling championship competition held annually between 1974 and 2004 for the so-called 'weaker' hurling teams in Ireland and organised by the Gaelic Athletic Association (GAA). It is contested by those county teams knocked out in the first round of the All-Ireland Senior Hurling Championship and the winner is 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 and these teams now play in the Joe McDonagh Cup which is the successor competition to the championship.
The title was won by 11 different teams, 6 of which won the title more than once. The all-time record-holders are London, who won the competition 5 times. The history of the championship was bookended by victories for Kildare, winners of the first title in 1974 and the last in 2004.
