All-Ireland Senior Camogie Championship - Format

Format

The counties participate in a group series with the top four progressing to the All-Ireland Semi-Finals. The eight teams were divided into two groups of four in 2009. In every other year the teams were placed in a single group of between six and eight teams. The first two championships were played on an open draw basis until in 1934 the championship was changed to the traditional quadro-provincial structure traditional to Gaelic Games. Following the withdrawal of Connacht from the inter-provincial senior semi-finals the competition changed to an open-draw knockout system in 1974.
