The IRFU Women's Interprovincial Series, previously known as the IWRFU Interprovincial Championship, is the top level women's rugby union competition in Ireland. It is organised by the Irish Rugby Football Union. It is the women's equivalent of the former IRFU Interprovincial Championship.

The competition takes place every December and features four teams representing Connacht, Leinster, Munster and Ulster. ^{[1] [2]} The competition effectively acts as a selection trials process for both the Celtic Challenge regional cross-border competition featuring the Wolfhounds and Clovers teams, and the Ireland women's national rugby union team that competes in the subsequent Women's Six Nations Championship. ^[3]

Since 2016 the IRFU has also organised a similar under 18s competition. ^[4]

Format

The competition has historically used a round-robin format, similar to the one used in both the Six Nations Championship and the Women's Six Nations Championship. Each team playing the other three teams once. The following year the fixtures are reversed. ^[1]

In recent seasons, the competition has also featured playoffs, consisting of a third-place playoff or minor final, and a final ^{[5] [6] [7]}
