Top 10 Greatest Heavyweight MMA Fighters of All Time
It's the most brutal chess match you'll ever watch. Two giants locked in a cage, looking to rearrange each other's jawlines while avoiding having their lights switched off. Heavyweight MMA is a different beast. One punch can end a fight. One takedown can flatten a career. And the legends who've survived, thrived, and bulldozed through this division? They're made of something else entirely.You're not just picking your favorites here. You're weighing knockouts that echoed across arenas, title reigns that felt more like hostage situations, and fighters who didn't just beat the best. They scared them. Some ruled with cold precision. Others with chaos in their eyes and dynamite in their fists. A few came out of nowhere, steamrolled names you thought untouchable, then vanished just as fast.
So throw your vote behind the ones who raised the bar. And often the blood pressure of anyone watching.

I think he has the best instinct in combat sports. We saw it, for example, in the Randleman fight, where he made the right decisions in a situation most people wouldn't survive.
Greatest MMA heavyweight of all time. No debate. No one else is even close. Ten years, 32-fight win streak. RINGS, PRIDE, and AFFLICTION heavyweight champion. No heavyweight will dominate for ten years across three organizations the way he did.
The only fight he lost was his first-ever fight, but he beat that opponent later in his career. I am an MMA fanatic and absolutely no one can beat him. His record is 47-0 and he is still fighting in Strikeforce. Stop hating!
A deserved third place on this list. He will be remembered as one of the most explosive fighters in heavyweight history and surely as the best striker in heavyweight history.
What is Lesnar doing at number two? Mirko would kick his head off his shoulders!
Ends most of his fights in knockouts and has been in many MMA battles.

Freak of nature. The UFC has not found another heavyweight who is as agile, intimidating, and a crowd puller as him.
The current UFC heavyweight champion and seems impossible to defeat at this time.
He has kicked Goldberg's ass down and now he will destroy everyone in MMA.

Injuries and long layoffs have played a significant role in Cain's fighting career. If it weren't for those setbacks, Cain would have easily established himself as the greatest heavyweight fighter in MMA. He might even be the best MMA fighter ever.
It was the high altitude conditions that caused Cain to lose to Fabricio Werdum. Watch what happens when the rematch takes place elsewhere.
Laugh out loud! You don't know who Cain Velasquez is? He defeated Lesnar, Dos Santos, and Antonio Rodrigo Nogueira!

Why isn't he number one? He schooled Cain Velasquez for the heavyweight title and made Fedor submit.
Should be number one. Beat Fedor and Cain Velasquez and, at the moment, is the UFC heavyweight champion.

He's one of the most respected fighters on the planet. The guy has so much respect to add to his amazing fight resume.
Has held multiple titles in the UFC and has been around for a long time.

If he can continue his title defenses to include N'Gannou and Velasquez, he will be number one of all time.

The greatest striker in the division right now. He has beaten six former champions. The term reigns supreme.

Dan "The Beast" Severn is so underrated. He should be at least in the top five.
The Newcomers

Big Nog should be at number two, second only to Fedor. It's a joke having Lesnar at number two when he shouldn't even be on this list.
Legendary. His wins over Bob Sapp and Mirko Cro Cop showed the greatest heart in MMA history. Having Lesnar ranked ahead of Minotauro is a joke in very bad taste.
He fought so many wars and was the only fighter to hold both PRIDE and UFC heavyweight titles. Enough said.
Shattered Cro Cop, and all of his past victories have been exceptional.
When Gonzaga knocked out Cro Cop, it sent chills down my spine. That was the ugliest, most devastating knockout ever. Not only did Cro Cop get knocked out cold, but he also broke his leg on the way down. Ouch.

A multiple-time UFC champion who has defeated many greats.

Should be higher. Top heavyweight fighters are: Fedor, Stipe, Cain, Randy, Mirko, Antonio, Junior, and Dan. Maybe I've forgotten some guys.
The best boxer in the history of heavyweight MMA. Enough said.

This guy is 250+ lbs, yet fights like a featherweight. He brought the word "submission" to the heavyweight world. He made Lesnar tap and made Abbott tap. It is truly unfortunate what happened to him. I hope he fully recovers one day.
Great submission expert and has done what others have yet to do: defeat Lesnar. A former two-time UFC heavyweight champion.


Heavyweight tournament winner in the older UFC and a living legend. Defeated Couture.

A former UFC champion who ripped through most of his competition very well.
