MMA fighters in the UFC need to be experienced in both striking and grappling. Muay Thai, Taekwondo, karate, boxing, and kickboxing are some of the best martial arts that can serve as a striking base.
In this article, I will focus on kickboxing and who are the best MMA fighters that have used kickboxing in the UFC.
I have to mention that the given list of best kickboxers in the UFC is not ordered. I took many factors into consideration, like their UFC and MMA resume, kickboxing resume, striking technique and diversity, striking accuracy and volume, etc.
Also, worth considering is that when I say “kickboxer” I refer to both Dutch and American kickboxing, with some Muay Thai background as well.
So, let’s take a closer look at fighters who made it to the list.
Also, I made lists similar to this for a few martial arts. Take a look at best Muay Thai fighters in the UFC, best boxers in the UFC, best BJJ practitioners in the UFC, and best wrestlers in the UFC.
Mirko “Cro Cop” Filipovic
Division: UFC Heavyweight, Pride Heavyweight (retired)
MMA record: 38-11 (2 draws and 1 NC)
I start my list with one of the deadliest kickers in the history of MMA, Mirko “Cro Cop” Filipovic. Cro Cop’s signature move was left high kick, once famously described as “right leg, hospital; left leg, cemetery.”
During his career, Mirko fought the best heavyweights of all-time in the UFC, Rizin, Pride, Bellator, and K-1. He is widely considered as one of the best MMA heavyweights of all time.
Cro Cop is the 2006 Pride Open-Weight Grand Prix Champion, the 2012 K-1 World Grand Prix Champion, and the 2016 Rizin Openweight Grand Prix Champion becoming the second fighter in the world to win mixed martial arts and kickboxing championships and tournaments.
He started his career as an amateur boxer where he had a 48-8 record with 31 wins coming by knockout. Mirko then proceeded to have a kickboxing career where he accumulated a 26-8 record (13 KOs).
In his glorious MMA career, Mirko fought 52 times, and he won 38 times. Out of his 38 wins, 30 come by a knockout, which is impressive.
Through his career, Mirko put dozens of his opponents to sleep using his head kick skills. Just take a look at the breakdown of his head kick technique:

Anderson “The Spider” Silva in his prime is one the best fighter in the history of MMA. He is a former UFC Middleweight champion and holds the record for the longest title reign in UFC history with 2457 days as the champion.
His champion era began in 2006 and lasted all the way to 2013. In that span of time, he defended the title for the second-best ever number of 10 times and won 16 times in the process.
Silva uses a combination of Muay Thai, Capoeira, and Taekwondo as his kicking base. Out of his 34 career wins, 23 come by knockout.
Anderson Silva is one of the deadliest KO artists in history. His ability to put his opponent down anytime, from any angle is impressive. When it comes to kicking, he is one of the most creative MMA fighters ever.
To best describe Silva’s greatness inside the Octagon, just take a look at all the records he has:
- Second most title defenses in UFC history (Middleweight, 10 times),

Alistair “The Demolition Man” Overeem
Division: UFC Heavyweight, Pride Heavyweight, Strikeforce Heavyweight, Dream Heavyweight
MMA record: 47-19 (1 NC)
Alistair Overeem might be the best kickboxer in the history of MMA.
The Dutch kickboxer is a former Strikeforce Heavyweight Champion, DREAM Heavyweight Champion, K-1 World Grand Prix Champion, and one of only two fighters to hold world titles in both MMA and K-1 kickboxing at the same time.
He holds dual victories over MMA legends Fabricio Werdum, Mark Hunt, and Vitor Belfort. Overeem has also beaten former UFC champions Andrei Arlovski, Junior dos Santos, Frank Mir, and Brock Lesnar.
Alistair favors kicks to the body and legs, as well as knee strikes from the clinch, which have been described as “devastating.”
His most famous finishing technique used to be the left knee to the midsection, by which he ended many fights, but Overeem switched to the left body kick instead in the late on his career.
He is also proficient with left overhands and hooks once his opponents are worn down.
Out of his 47 career wins, 25 came by KO. Overeem also holds the record for being the only fighter to simultaneously hold three championship belts (Strikeforce, K1, and Dream).
