The 2025–26 Celtic Challenge will be the fourth season of the Celtic Challenge, a cross-border women's rugby union competition with teams from Ireland, Wales, and Scotland. The six team tournament features a full double round robin fixture series, with each team playing the others both home and away. For the first time, however, the competition will include a single elimination play-off with semi-finals and a grand final to be held in Edinburgh.

Wolfhounds enter the competition as two–time defending champions.
