San Diego State University has a proud history of basketball, with multiple appearances in the NCAA tournament. The Aztecs, as they are commonly known, have been a force to be reckoned with in college basketball, and their performances in the NCAA tournament have been nothing short of spectacular.

Since their first appearance in the NCAA tournament in 1985, San Diego State has made a total of twelve appearances in the tournament. This is a testament to the consistency of the program, which has been able to produce competitive teams year after year. The Aztecs have consistently been one of the best teams in the Mountain West Conference, and their performances in the NCAA tournament have been a reflection of their dominance in the conference.

San Diego State's first appearance in the NCAA tournament came in the 1984-85 season, when they finished the regular season with a 23-6 record. They were awarded an at-large bid to the tournament and faced off against Illinois State in the opening round. Unfortunately, they were unable to advance beyond the first round, losing to Illinois State by a score of 70-61.

It would be another 17 years before San Diego State would return to the NCAA tournament. During this time, the program struggled to find success, and it wasn't until the arrival of head coach Steve Fisher in 1999 that things started to turn around. Fisher was able to build a winning culture at San Diego State, and the program began to see success on a consistent basis.

In 2010, San Diego State returned to the NCAA tournament for the first time in 12 years. They were seeded 11th in the West Region and faced off against Tennessee in the opening round. The Aztecs were able to pull off the upset, winning the game 62-59. They would go on to lose to Duke in the second round, but their performance in the tournament was a sign of things to come.

Over the next decade, San Diego State would become a regular in the NCAA tournament. They made the tournament eight times between 2010 and 2021, with their best performance coming in 2011 when they reached the Elite Eight. Led by future NBA star Kawhi Leonard, the Aztecs defeated Northern Colorado, Temple, and Connecticut to reach the Elite Eight, where they lost to eventual national champion UConn.

San Diego State continued to have success in the NCAA tournament, making the tournament again in 2014 and 2015. In both of those years, they advanced to the Sweet Sixteen before being eliminated. In 2021, San Diego State made their most recent appearance in the NCAA tournament, where they advanced to the Sweet Sixteen before being eliminated by Syracuse.

In addition to their success in the NCAA tournament, San Diego State has also had success in the Mountain West Conference. They have won nine conference championships since joining the conference in 1999, and they have consistently been one of the top teams in the conference.

Overall, San Diego State's success in the NCAA tournament is a testament to the quality of the program. They have consistently produced competitive teams, and their performances in the tournament have been a reflection of their dominance in the Mountain West Conference. While they have yet to win a national championship, San Diego State has established itself as one of the top programs in college basketball, and they are sure to be a force to be reckoned with in the years to come.
