Greatest Heavyweight Boxers of All Time

The Top Ten

1 Muhammad Ali Muhammad Ali (January 17th 1942 - June 3rd 2016) was an American former professional boxer . He was generally considered among the greatest heavyweights in the history of the sport.

Ali is the greatest, but styles make 1:1 matchups. And the one match up that was a bad one for Ali was Smokin’ Joe Frazier whose left hooks got to him with devastating regularity.

He is probably the greatest. I was not a fan as I did not like his big mouth and putting down his opponents. I was always a Joe Frazier fan. Although he won 2 of the 3 bouts against Joe, he took some severe punishment from Joe. I enjoyed that!

Did not know how to avoid Frazier’s left hook. Took some heavy punishment to the Head and jaw from Joe Frazier as a result.

Ali is the only fighter in the world who can be compared with any greatest skillful fighter... The most skillful and confident athlete in the world... He should be undefeated but unfortunately he didn't but cleaned his career by defeating all them who defeated him... I think after Ali, tyson is the only man ewho can be compared with any great fighter.. But tyson can't defeat Ali... This is 1000% assurity

2 Mike Tyson Michael Gerard Tyson (born June 30, 1966) is an American former professional boxer who competed from 1985 to 2005. He reigned as the undisputed world heavyweight champion and holds the record as the youngest boxer to win a heavyweight title at 20 years, four months and 22 days old.

How can anyone say that Tyson would beat Ali when he couldn't even beat Holyfield? Ali would Throttle the little runt! Tyson lacks heart when faced with adversity in the ring. When has Tyson arose from a knockdown to win? The answer is NEVER! Ali, Foreman, Holmes, and even Buster Douglas have gotten up off the canvas to defeat their opponents. Heart is a major criteria for being considered an all-time great, something Iron "Bite" Tyson sorely lacked!

Prime Tyson (late 80's) was the GoAT. Most people today forget about that Tyson, and only remember/know about post-prison Tyson who was only a shadow of his former 80's self.

I gotta say tyson man... I agree 100 percent that rocky would kick alis ass.. But if not for don king, his original trainer custer or somebody his name? Anyway an women.. Yea oh an that muslim stuff I think mike would have went on to be the greatest but that's a lot of ifs.. So probably rocky

Tyson '85 - '89 was unstoppable. During that time, he easily had GoaT skills. No heavyweight from any era at any point would've beat Tyson when he was 20 - 23 yo. Period. After he got rid of Rooney it was all down hill though. D'amato's death hit Mike hard too. For whatever reasons, Tyson peaked early and burned out quick, but at his apex ('85 - '89) he was invincible and would've beaten anyone!

3 Rocky Marciano

People forget that he beat Joe Louis. After the fight during an interview Louis stated he would not have been able to ever beat Marciano, even if he had his best fight. In doing the filming for the computerized match against Ali, the retired Marciano knocked Ali down, while Ali was unable to knock down Marciano. Ali lost several fights, Marciano lost none.

Undefeated and never ducked a fight or hid from anyone doesn't get the credit he deserves same can be said for Larry Holmes except for the one fixed loss.Tyson a joke Don King would not let him fight forty or fifty something George Forman should not be in the top 20

hei s definitely the greatest of all time, there was a computer animated fight between him and Ali and he whooped Ali's ass!

Mike Tyson is no joke. Floyd Mayweather is a joke but Rocky Marciano is the greatest of all time. Manny Pacquiao is very talented as well

4 Joe Louis

Joe Louis was heavyweight champion for 12 years between 1937 to 1949 and he made 25 successful defenses of his world title a record that still stands in 2017, 68 years after he retired.

Record speaks for self not mention fighting in a time of extreme racism.

Also fought a lot of old guys and no big names.

Of all the boxers I has seen Joe was the best

5 George Foreman George Edward Foreman is an American former professional boxer who competed from 1969 to 1977, and from 1987 to 1997. Nicknamed "Big George", he is a two-time world heavyweight champion and an Olympic gold medalist.

Foreman destroyed Frazier twice and punched himself out with Ali. Foreman beats Ali in rematch. Foreman also wins past 40. Ali couldn't do that

Foreman is one of the greats I am happy he is at least in the top 5

Ali was a bum

6 Evander Holyfield

He might not be the greatest heavyweight of all time but he dominated Tyson

Tyson was scared Of Evander

Very underrated fighter. Holyfied dominated the light heavyeight division for years, then moved up to heavyweight. There he dominated Tyson(twice) and defeated Douglas, Lewis, and Bowe which were all much bigger than he was. If anything he was arguably the toughest fighter in history.

7 Joe Frazier Joseph William Frazier, nicknamed "Smokin' Joe", was an American professional boxer who competed from 1965 to 1981. He reigned as the undisputed heavyweight champion from 1970 to 1973, and as an amateur won a gold medal at the 1964 Summer Olympics.

Joe Frazier was my favorite. I became a fan after he pulverized Bob Foster. I always felt that would beat Ali. He oozed such confidence before their first fight against Ali. It shook Ali for sure. No one made Ali doubt himself as much as Joe did.

My favorite. Emerged undefeated after the fight of the century against Ali in which he whipped Ali.

Aggressive boxer always moving ahead and forcing opponents on the defensive. Wicked left hook and body shots.

One of the greatest boxers, constantly moving forward and applying pressure. Won the bout of the century against Ali and became the undisputed heavyweight champion of the world.

Used his left hook to torment Ali who had never taken such a beating from anyone else until then.

8 Lennox Lewis

Lennox is number 1 in my opinion, I loved watching him beat Tyson to a pulp.

Only ali defeated better boxers than him and both tyson and holyfield refused to face him sooner and of course he is the only in history who defeated the next king of the division just look what happened to louis ali holmes tyson and others at age 37-38

Great boxer. I became a fan after seeing his absolute destruction of Razor Ruddock. Ruddock was clearly intimidated by Lewis going into the fight while Lewis was remarkably calm and focused. Lewis just ended Ruddock’s career with some brutal blows. The same Ruddock who had done well against Tyson was ruthlessly brushed aside.

Because he is not American he is not popular in America even he is not white to be popular in Europe only true boxing fans know that only Ali is in his level

9 Larry Holmes

Poor Holmes, never gets credit. I prefer brawlers, but Holmes would probably surprise us in a elimination match between the greats of all time. That said, He did not fight big names when in the prime. When he fought Ali, Ali was old. When he fought Tyson, he was old.

Holmes never got the credit he should have.Liston was much older when he was beat by then Clay than Ali was when beat by Holmes.No one thought Clay could beat Liston and when he did he said I'm the greatest and that stuck with him,Ali was a great promoter also.The way he moved he looked good in the ring.Ali was very tough also,he could take a lot of punches.Holmes never lost to stiffs and had to regain his title,he kept it longer than pretty much anyone ever did.Tyson had trouble against good boxers.Lewis was a great fighter but didn't have the size,neither did Rocky.Ali was the greatest but Holmes was the best ever! He needs to be moved up.

10 Wladimir Klitschko

Come on Vladimir. Fight to eventually whoop Tyson fury. Only you can destroy this arrogant idiot. Train hard and Bury him. Please.

Kinda of impressed with skills at an old age.

There was not enough competition for him to shine.

6'6 disciplined boxing...great chin and stiff when requires.

The Contenders

11 Jack Dempsey

Jack dempsey is the best

12 Sugar Ray Leonard Ray Charles Leonard, best known as "Sugar" Ray Leonard, is an American former professional boxer, motivational speaker, and occasional actor.

This must be a mistake. This man was never a Heavyweight.

The greatest heavy weight of all time

Sugar Ray was great but he wasn't a heavyweight, not even close.

He knocked out that bum...whats his name...Muhammad Ali

13 Jack Johnson
14 Gene Tunney
15 Sonny Liston

He threw both fights against Ali. In the first fight, the official reason was his shoulder was ripped in the tendon, but his trainer later said: "The shoulder thing was BS."

In the second fight the "phantom punch" Liston clealy goes down but rolls down again and later said: "i threw the fight because of the Black Muslim."

He was a force, one of the best punchers, better than Joe Louis, George Foreman and Mike Tyson in a test by ESPN, and he could jump up and kick his hands when he held them up.

He was a legend, knocking out Floyd Patterson in 1 round twice for the Heavyweight championship.

One of the greats, and still the most intimidating.

16 Roy Jones Jr. Roy Levesta Jones Jr. is an American former professional boxer, boxing commentator, boxing trainer, rapper, and actor who holds dual American and Russian citizenship.

He was a damn good boxer and a great man thanks for your time in the ring

17 Tyson Fury
18 Vitali Klitschko

Arguably, better than Lewis. Outpointing Lewis before injury stoppage in their fight, but he lost to good fighters while Lewis lost to average ones.

He never Kiss the floor!

19 Anthony Joshua

20 Tim Witherspoon
21 Andy Ruiz Jr.

Heavyweight Champion

22 Robert Helenius
23 Floyd Mayweather
24 Jim Corbett
25 Tommy Morrison
