10. Gary Goodrich vs. Paul Herrera – UFC 8 (1996)
I had to throw in a highlight like this for fans of the “old school” UFC era because techniques like these were so mind blowing at the time. Gary Goodrich put Paul Herrera into a crucifix position and then proceeded to deliver multiple elbow strikes to his head. We had never seen something like this before. I remember watching this as a teenager and being utterly shocked at the violence of this fight.
9. Spencer Fisher vs. Matt Wiman – UFC 60 (2006)
It wasn’t the first flying knee KO in UFC history (that would belong to James Irvin in UFC 50), but this one is the wildest and most memorable. Watch Fisher absolutely go for broke, launching his body through the air at Wiman and connecting for a brutal KO.
8. Cheick Kongo vs. Pat Barry – UFC on Versus 4 (2011)
One of the wildest endings to any fight in the UFC happened on UFC on Versus in 2011. Cheick Kongo was badly shaken by a few hard strikes from Pat Barry and looked like he was close to being finished. Instead, he somehow managed to stumble to his feet and throw a “Hail Mary” type haymaker, turning the tables and knocking out Barry.
7. Francis N’Gannou vs. Alistair Overeem – UFC 218 (2017)
It’s rare to see an uppercut style KO in the UFC, and this one was spectacular. Dubbed the “uppercut from hell”, this highlight reel KO made it to many top KO of the year lists.
6. Holly Holm vs. Ronda Rousey – UFC 193 (2015)
Ronda Rousey was the first female UFC superstar, and going into this fight she seemed unstoppable. To everyone’s surprise Holly Holm put on a masterclass in counterattacking. With razor precision she tore Rousey apart, culminating in this head kick KO. This KO shocked the UFC and began the demise of Rousey.
5. Anderson Silva vs. Forrest Griffin – UFC 101 (2009)
This KO is added because of the supreme level of skill on display. Anderson Silva at his peak was as good as any fighter in the UFC and he shows it against Forrest Griffin in UFC 101. Silva toys with Griffin, making him look like an amateur before knocking him out with a well-placed right hand.
4. Gabriel Gonzaga vs. Mirko Cro Cop – UFC 70 (2007)
This head kick KO was a shock to fight fans – because it went against Cro Cop. Before this fight, Cro Cop was well known as one of the best head-kick artists in the game. Gonzaga gave Cro Cop a taste of his own medicine with this devastating KO kick.
3. Edson Barboza vs. Terry Etim – UFC 142 (2012)
One of the most famous KOs in UFC history, this beauty is a must for any top KO list. Barboza executes a flawless spinning hook kick hitting Etim right in the temple.
2. Lyoto Machida vs. Randy Couture – UFC 129 (2011)
In 2011, Lyoto Machida was working to regain his title contender status, having lost to Mauricio Rua and Quinton “Rampage” Jackson the year prior. He faced off against Randy Couture in UFC 129 and landed this fantastic jumping front kick for the KO. It was reminiscent of the “crane kick” from Karate Kid.
1. Dan Henderson vs. Michael Bisping – UFC 100 (2009)
Perhaps the most memorable KO in UFC history came during the historic UFC 100 event. Henderson and Bisping coached opposite each other in The Ultimate Fighter which set up this match up. As fate would have it Bisping would suffer an extra brutal knockout from a patented Henderson overhand right…aka the “H Bomb.”
