Buster Douglas
Arguably, Mike Tyson's career's biggest upset occurred on February 11, 1990, in Tokyo, Japan, when he succumbed to a shocking defeat against overwhelming underdog Buster Douglas. Heading into the fight, Mike Tyson had a perfect 37-0 record and held the WBA, WBC, IBF, and lineal heavyweight titles.

To the shock of spectators around the world, Douglas knocked Tyson out in the 10th round of the fight to cause what is widely regarded as one of the biggest upsets in combat sports history.
While there were rumors that Tyson was going through a personal crisis heading into a fight, the upset was still big enough to send shockwaves through the world of boxing at the time.
Evander Holyfield
Mike Tyson had seemingly recovered from the loss against Douglas very well. Iron Mike picked up seven straight wins following the shock defeat that ended his undefeated streak. However, on November 9, 1996, Tyson faced Evander Holyfield at the MGM Grand Arena in Las Vegas.
The fight turned out to be a violent slugfest, as Holyfield started to pick Tyson apart in the later rounds. He managed to finish Tyson in the 11th round to pick up one of the biggest wins in heavyweight history.
Tyson wanted a quick turnaround to rematch Holyfield, and his demands were met. The pair squared off once again at the MGM Grand Arena on June 28, 1997. Mike Tyson looked good in the initial rounds and was on his way to picking up an impressive win in the rematch before Holyfield head-butted him.
An infuriated Tyson tried to land haymakers on his opponent but failed to do so. Instead, bit Holyfield's ear when they were caught in a hold. However, the fight continued until Tyson repeated the same actions, biting Holyfield's other ear from the clinch.
Tyson suffered a DQ loss in the third round and lost his boxing license. He was also fined $3,000,000 as a punishment for displaying unsportsmanlike conduct during the fight.
Lennox Lewis
While these were the three fights that Mike Tyson lost in his prime, he suffered three more losses towards the end of his career. He got knocked out in what was his last shot at the heavyweight title against Lennox Lewis on June 8, 2002. Tyson was 35 at the time and faced Lewis, who was in the best shape of his life.
Danny Williams and Kevin McBride
His other two defeats came against Danny Williams and Kevin McBride in 2004 and 2005, respectively. Mike Tyson faced Williams after a 17-month layoff and got knocked out in the fourth round of the fight after suffering a knee injury early on in the fight.
After the sixth round against McBride, he retired in what was the final fight of his career as a professional boxer.
