The 2015 Women's Premier League Rugby season was the seventh season of the Women's Premier League in the United States. It began on September 12 and involved eight teams.
This was the first year the WPL went without promotion or relegation. The eight teams were divided into two conferences, Red and Blue, comprising four teams. They each played six conference games, one home and one away. The WPL season occurred in the fall, concurrently with the regular women's club season, with the National Championship being held in November 13–15.
For the Finals, teams were seeded based on the results of their conference during the regular season. The top four teams competed for the Cup and the bottom teams for the Bowl.
