Provincial Championships

Connacht, Leinster, Munster and Ulster each organise their provincial championship.

For clarity, the format is explained in the provincial sections below.

Qualifiers

All teams except the provincial champions enter the All-Ireland qualifiers. The final four winners from the qualifiers re-enter the All-Ireland championship at the quarter-final stage. All matches are knock-out.
