The All-Ireland Intermediate Ladies' Football Championship is a knock-out competition in the game of Ladies' Gaelic football played by women in Ireland. The series of games are organised by Ladies' Gaelic Football Association (Irish :Cumann Peil Gael na mBan)) and are played during the summer months with the All-Ireland Final being played on the last Sunday in September or the first Sunday in October in Croke Park, Dublin.

The winners of the competition are presented with the Mary Quinn Memorial Cup.

The All-Ireland Intermediate Championship was preceded by the All-Ireland Senior B Championship. However, both are different competitions. The All-Ireland Intermediate Championship commenced in 1997, however this was not renamed from the All-Ireland Senior B Championship, but was instead a new and different competition. The All-Ireland Senior B Championship was for counties who had a second county team or counties who did not play Senior Championship competition. (Source: LGFA Operations Co-Ordinator, June 2023)
