The 2011 NCAA National Collegiate Women's Ice Hockey Tournament involved eight schools in single-elimination play that determined the national champion of women's NCAA Division I college ice hockey. The Frozen Four was hosted by Mercyhurst College at Tullio Arena in Erie, Pennsylvania. The Wisconsin Badgers defeated the Boston University Terriers 4âÂÂ1 for their fourth national championship. It was the first (and as of , only) time that two players were named the Most Outstanding Player with Wisconsin's Meghan Duggan (two goals, three assists) and Hilary Knight (one goal, four assists) each receiving the honor.
The winners of the ECAC, WCHA, and Hockey East tournaments all received automatic berths to the NCAA tournament. The other five teams were selected at-large. The top four teams were then seeded and received home ice for the quarterfinals.
Quarterfinals held at home sites of seeded teams
