The 2015 Big Sky Conference women's basketball tournament was held March 11–14, 2015.
The women's tournament ran this year with a Wednesday-Friday-Saturday format because Montana hosted both tournaments, having won the women's regular-season title outright and earned men's hosting rights by winning a tiebreaker with regular-season co-champion Eastern Washington.
With the move to an 8-seed schedule, the Big Sky also chose to go with the regular 8-seed tournament most other conferences use.
[3] The 2015 tournament was the last to be held at campus sites, and the last in which certain teams were excluded for poor performance.
Starting with the 2015–16 season, the Big Sky men's and women's tournaments both expanded to include all conference members (barring NCAA sanctions or self-imposed postseason bans), and both tournaments will be held at a predetermined neutral site.
