Since this list isn't narrowed down to a specific weight class, a lot of thought had to go into classifying all the bouts and picking the best of the best. Without further ado, here are the top 25 greatest boxing matches of all time!

25. Israel Vazquez vs Rafael Marquez III

The second bout between Mike Tyson and Evander Holyfield is an iconic one. Originally nicknamed as "The Sound and the Fury" before being infamously named "The Bite Fight" this was the fight for the WBA Heavyweight Championship.

This was probably one of the most insane fights in boxing history as in the third round, Tyson bit off part of Holyfield's ear. This got Tyson disqualified and made him lose his boxing license even though it was later reinstated to him. One of the most bizarre things ever seen in a boxing ring!

This was the most money ever offered to a fighter at the time with $6 million dollars going to Ali for the fight. This was also an extremely close fight and many boxing fans argue about who actually deserved to win it. After 15 grueling rounds Ali took the victory.

20. Erik Morales vs. Marco Barrera

16. James Corbett vs John Sullivan

James Corbett and John Sullivan fought in 1892 for the World Heavyweight Championship. Boxing back then was nothing like it is now and it was even outlawed in many states.

Corbett won the fight by knocking out Sullivan in the 21st round, yes, the 21st. These fights could sometimes go up to 75 rounds and would end when an opponent was knocked out! Gloves were also recently added as until 1889 the title championships had been bare-knuckled.

15. Rocky Marciano vs. Joe Walcott

This fight was great because of how divided it was before it even started. Walcott was the champion at the time and he stated how Marciano "couldn't fight" and even stated that if he got beat by him to "take my name out of the record books".

Walcott gave Marciano the first knockdown of his career midway throught the fight. Both fighters were cut and hurt and by the seventh round Rocky said he couldn't see. Marciano got a perfect hit on Walcott's chin and knocked him out cold to win the fight.

14. Sugar Ray Leonard vs. Marvin Hagler

However, Leonard took the first couple of rounds and then finished the fight by boxing smartly. It was a huge upset that no one expected but Sugar Ray took the split decision win and Hagler never fought again afterwards.

13. Zolani Tete vs. Siboniso Gonya

Zolani Tete vs Siboniso Gonya set a world record in this fight. This bout was for the WBO World bantamweight title that Tete was defending. There isn't much to say about the fight itself as it didn't last very long.

In only 11 seconds, Tete knocked out Siboniso Gonya with his first and only punch of the entire fight. This was the fastest knockout ever seen in a world title fight and that is what makes this fight so iconic.

12. Joe Louis vs. Billy Conn 

At this point in time, Joe Louis was the heavyweight world champion and he had defended his title 17 times. Louis took the first two rounds but Conn showed that he was there to fight in the third.

For the first time ever, the champion Joe Louis was retreating and noticably hurt by Conn's strategic and powerful punches. Louis responded with a right that dazed Conn and then finished him off with perfect power punches to win the match. One of the most intense fights in history.

7. Jack Dempsey vs. Luis Firpo

Luis Firpo was the first Latin American fighter to challenge the world heavyweight title. The Argentine fighter dropped Jack Dempsey almost immediately in the first round to which Dempsey responded by dropping Firpo seven times in the space of a minute and a half.

Dempsey somehow recovered and in the second round he knocked Firpo out. The fight had 11 knockdowns in four minutes in what is one of the most historic and brutal fights the sport has ever seen.

6. Julio Chavez vs. Meldrick Taylor 

The first fight between Julio Chavez and Meldrick Taylor was a spectacular battle. The fight was exhilarating from the start with Taylor landing many clean punches on Chavez who endured them like a champ.

Taylor punished Chavez for most of the fight but Chavez also landed good combinations when the two got in close to trade blows. If the fight ended before the last round, Taylor would've won, but in the epic last round Chavez landed a devastating right with only 2 seconds left of the fight that won him the fight.

5. Sugar Ray Leonard vs. Thomas Hearns

Sugar Ray Leonard and Thomas Hearns were the two biggest boxers at the time and this was a very anticipated fight. The fight was pretty even until the 6th round when Leonard struck Hearns on the chin leaving him stumped for the round.

Round thirteen saw Sugar Ray stun Hearns with a right hand that followed by him throwing 25 punches and knocking him down. Round fourteen was more of the same with Hearns taking a beating until the referee stopped it and raised Leonard's hand for the win.

4. George Foreman vs. Muhammad Ali

This was the fight that crowned Muhammad Ali as the heavyweight champion of the world for the second time in his career after knocking out George Foreman in what was billed as the "Rumble in the Jungle". Ali was the underdog coming into the fight but you can never undersell a legend like him.

Foreman landed some very hard punches on Ali, but that was the plan all along. Ali waited for Foreman to get tired and then in the eighth round he answered with a barrage of quick combinations that laid Foreman on the mat to give Ali the win.

3. Arturo Gatti vs. Micky Ward 

The ending of this fight is magnificent. Gatti started off better and the end of the third round was a slug fest between the two fighters. Gatti gets saved by the bell in the eigth round after some monster shots to the head by Ward.

In the last round, both fighters just unleashed as many shots as they could on each other and as soon as the final bell rang, they both fell into each other's arms. Ward was declared the winner and the two ended up having two more fights.

2. Joe Frazier vs. Muhammad Ali

In the 15th round Frazier hit Ali with one of the most iconic left hooks in boxing history. Ali somehow got up though, and when it was all over Frazier won via unanimous decision. The fight was outstanding and widely regarded by many as the biggest boxing match in history.

1. Muhammad Ali vs. Joe Frazier III

The "Thrilla in Manila" was the third fight between the two boxers after Frazier won the first bout and Ali the second. Although it didn't have the same anticipation as their very first fight, both boxers showed why they are legends in this one. Ali started strong again on the first rounds but in the middle ones Frazier bashed Ali with powerful body shots.

Ali regained momentum in the last couple of rounds and towards the end of the fight Frazier could barely see from how swollen shut his eyes were. Eddie Futch, Frazier's trainer, asked the referee to stop the fight after the 14th round to give Ali the win. This iconic fight gave Ali the win in their trilogy and is the greatest title fight in history.
