An upset is a victory by an underdog team. In the context of the NCAA Division I women's basketball tournament, a single-elimination tournament, this generally constitutes a lower seeded team defeating a higher-seeded (i.e., higher-ranked) team; a widely recognized upset is one performed by a team ranked substantially lower than its opponent.

This is the list of victories by teams seeded 11 or lower in the first round and second rounds of the tournament, as well as those by teams seeded 8 or 9 against 1 and 7 or 10 against 2 seeds in the second round, since it expanded to 64 teams in 1994; as these low-seeded teams were automatically paired against higher-seeded teams at the start of the tournament, their opening victories are almost always considered upsets. Most victories by these teams in later rounds were usually against better seeded opponents as well. The list also includes victories by teams seeded 8 or lower in the Sweet 16 (the four regional semifinals), teams seeded 7 or lower in the Elite Eight (the four regional finals), and teams seeded 6 or lower in the Final Four. All teams are listed by athletic brand names they used at the time of their wins, which do not always match those in use today.

The NCAA defines a tournament "upset" as a victory by a team seeded 5 or more lines below its defeated opponent.

The first 16 seed ever to win a game in an NCAA Division I basketball tournament was Harvard in 1998 against Stanford. According to an Associated Press retrospective on the 10th anniversary of the game in 2008, "The difference between the teams was much smaller than usual for a No. 1 and a 16 seed."^[1] Harvard had two years of tournament experience and the nation's leading scorer that season in Allison Feaster. Stanford suffered two devastating injuries during the run-up to the tournament. First, Vanessa Nygaard tore an ACL in the Cardinal's final regular-season game against Oregon State. Because the extent of her injury was not known at the time the tournament field was selected, the Cardinal still received a 1 seed. Then, in the team's first practice after the tournament selection, leading scorer and rebounder Kristin Folkl also tore an ACL.^[1]

Other than Harvard beating Stanford in 1998, no losing #16 seed has even lost by single digits and/or taken a game to overtime, with the closest margin of defeat being a 12-point loss by #16 Grambling to #1 Texas Tech in the same tournament.

No #14 seed has beaten a #3 and no #15 seed has beaten a #2 seed, but they have come close.

• 2 points: #14 Seed
  • Austin Peay lost to UNC in 2003 (2 points, 72–70)
  • Eastern Michigan lost to Boston College in 2004 (2 points, 58–56)
  • Creighton lost to St. John's in 2012 (2 points, 69–67)
• Overtime games: #15 Seed
  • UTSA lost to Baylor in 2009 (5 points, 87–82). UTSA is the only #15 seed to take a game into overtime.
• 1 point: #15 Seed
