Biggest March Madness Upsets of All Time

March Madness is one of the most significant parts of college basketball; 64 teams, single-elimination, and the chance to be remembered forever make this one of the most popular tournaments in all college sports. Yet with the format, upsets happen all the time, and this list highlights some of those iconic games.

What are the biggest March Madness Upsets of All Time?

  1. UMBC vs. Virginia (2018)
  2. FGCU vs. Georgetown (2013)
  3. NC State vs. Houston (1983)
  4. Villanova vs. Georgetown (1985)
  5. Richmond vs. Syracuse (1991)
  6. Lehigh vs. Duke (2012)

1. UMBC vs. Virginia (2018)

The most recent game on this list, occurring in 2018 and possibly the most memorable one, featured UMBCs victory over Virginia. This win was historical, as going into the match, Virginia finished the season 30-2, was the #1 ranked seed in its bracket region, and a favorite to win the whole tournament. Conversely, UMBC was 24-10 in the regular season and a #16 seed going into the matchup. Virginia was a heavy favorite to win as a #16 seed had never beaten a #1 seed in the 1st round of the tournament, and the talent gap was seen as too large for UMBC to overcome. Yet when the game ended, UMBC claimed victory in a blowout fashion, beating Virginia 74-54 and cementing itself in the history books.

2. Florida Gulf Coast vs. Georgetown (2013)

The Georgetown Hoyas, the #2 seed in the South Region for the 2013 tournament, came against #15 seed Florida Gulf Coast University. This was a stunning upset as it was only the seventh time in March Madness history that a #15 seed defeated a #2 seed. The game was close throughout, and the Hoyas almost staved off defeat. However, in the game’s waning moments, a massive one-handed alley-oop dunk by Florida Gulf Coast forward Chase Fieler sealed the win for FGCU in this dramatic upset.

3. North Carolina State vs. Houston (1983)

One of the biggest upsets in the tournament final round was when the famous 1983 "Phi Slama Jama" Houston basketball team was handed a stunning loss by the hands of the NC State Wolfpack. The Houston team was a #1 seed, a heavy favorite, and loaded with talent featuring future NBA Hall of Famers such as Clyde Drexler and Hakeem Olajuwon. In comparison, the NC State team was a #6 seed, massively exceeding expectations for their tournament aspirations. The game was incredibly close and tied at 52 in the final seconds before Lorenzo Charles' dunk with one second left sealed Houston's fate.

4. Villanova vs. Georgetown (1985)

This iconic game from the final game of the 1985 tournament is fondly remembered by the nickname "The Perfect Game." It featured the future champion Villanova Wildcats, who shot an astonishing 9-10 from the field in the second half and stunned the 8-point-favorite Georgetown Hoyas by a narrow 2-point victory. The two teams previously played each other twice, with Georgetown winning both times in Big East Conference play. Villanova entered the tournament as a #1 seed, while the Wildcats' relatively underachieving season left them with a #8 seed ranking before their historic championship run.

5. Richmond vs. Syracuse (1991)

One of the worst losses in the Syracuse Orange fanbase and program is one of the most incredible wins and upsets for the Richmond Spiders. This 1991 first-round game saw the #2 seed Orange lose to the #15 seed Richmond Spiders, despite having the future 3rd overall pick in the NBA draft in Billy Owens, who was having a great season in his own right. After handing Syracuse a stunning loss, they became the first #15 seed to win in the 1st round and defeat a #2 seed; with many people stunned at the victory, the final score was 73-69.

6. Lehigh vs. Duke (2012)

This 75-70 upset of the Duke Blue Devils by Lehigh in the second round of the 2012 NCAA Tournament was shocking to the rest of the field and those watching at home. This was only the second time in NCAA history that a #15 seed defeated a #2 seed in the tournament. This massive upset was spearheaded by an incredible 30-point performance from future NBA star CJ McCullum, who handed a loss to a loaded Duke roster filled with future NBA players such as Seth Curry, Austin Rivers, and brothers Mason and Miles Plumlee. This staggering gap in talent among the two teams and the circumstances earn this game a rightful place as one of the greatest upsets in NCAA Tournament history.


What is the biggest upset in March Madness history?

In the long-standing history of the March Madness Tournament, the most remarkable upset ranking-wise was by the 2018 UMBC team. Their victory over the #1 seed Virginia was the first time in tournament history that a #16 seed had ever won against the #1 seed and remains the only team to do so. The biggest comeback in tournament history was held by Duke when they overcame a 22-point deficit to Maryland in the 2001 tournament.

Has a 16 seed ever beaten a 1 seed in March Madness?

The first round of the tournament is often the most exhilarating, and the prospect of a #1 seed losing to a #16 seed always ensures the stakes are high. Before the 2018 tournament, the #1 seed had never lost to a #16 seed. To this day, a #16 seed defeating a #1 seed has only happened once in March Madness history, with the UMBC Golden Retrievers being the only team to have accomplished this notable feat.

What is the average number of upsets that happen in March Madness each year?

An upset is always possible for any team in the tournament; it's part of the allure. Since the tournament was expanded to 64 teams in 1985, there has been an average of about 12-13 upsets per year, with most of these upsets occurring in the 1st round of games. The 2007 tournament had the fewest upsets in total, with only four teams claiming a win over a higher-ranked opponent. On the other hand, the 2014 and 2019 tournaments both hold the record for most upsets, featuring 19 total upsets each.
