1986 NCAA Division I men's basketball tournament

Cleveland State University became the first #14 seed to reach the Sweet Sixteen, losing to their fellow underdog, Navy, by a single point.

The lone #1 seed to not reach the Elite Eight, St. John's (West), was knocked out in the second round by #8 Auburn, which lost to #2 Louisville in the regional final.
