- March 20 – Wladimir Klitschko knocks out Eddie Chambers with a fierce left that hits Chambers in the temple with only five seconds left in the fight.

- April 17 – Kelly Pavlik loses to Sergio Martínez in a close fight for Pavlik's WBC, WBO, and Ring magazine middleweight titles. Martínez controlled the early rounds with quick in and out movements, refusing to heavily engage with Pavlik. Martínez managed to cut Pavlik's left eyebrow in the first round. Pavlik then started to mount a comeback in the middle rounds by blocking Martínez's punches more effectively. Pavlik spent most of his time headhunting trying to land a hard right, which did help Pavlik get a knockdown in the seventh round. In the late rounds Martínez came back and started to open up Pavlik's cuts more, making his face extremely blood. In the post fight interview Pavlik said he couldn't see due to the blood. Martínez ended up winning the fight with a unanimous decision.
- April 24 – Mikkel Kessler upsets Carl Froch by a unanimous decision to win Froch's WBC super middleweight title. The fight was part of the second-group stage of the Super Six World Boxing Classic.

This fight was later named the best super middleweight fight of 2010 by Ring magazine.
- April 30 – In a stunning upset, Fernando Montiel knocksout Hozumi Hasegawa ending his five-year, 10 title defense streak and taking his WBC bantamweight title.

- May 1 – Floyd Mayweather Jr. defeats Shane Mosley to continue his undefeated career streak. Mosley came out strong for the first two rounds—at one point making Mayweather's knees buckle—but Mayweather went on to control the fight.
- May 8 – Making his comeback after roughly 15½ months of being suspended, Antonio Margarito defeated Roberto Garcia to win the vacant WBC international super welterweight title.
- May 15 – Amir Khan dominates Paul Malignaggi to win by TKO in the eleventh round to retain his WBA light welterweight title for the second time. This was Khan's debut in the United States.

- June 5 – Miguel Cotto defeats Yuri Foreman by a ninth round stoppage due to a leg injury Foreman suffered during the fight. In an amazing display of will, Foreman refused to quit despite being in what he later called a "very sharp pain". A towel was thrown in the ring, but it was ruled to have come from an outside source, and the fight continued for another minute until being stopped officially. This was Cotto's debut at light middleweight. The fight was the first boxing match in the new Yankee stadium built in 2009, and the first match in either Yankee stadium since Ali/Norton 3 in 1976.
- July 31 – In a rematch of 2009's fight of the year, Juan Manuel Márquez defeats Juan Díaz for a second time to retain his WBO lightweight title and to win the WBA super world lightweight title.
- August 14 – Jean Pascal upsets Chad Dawson by a technical decision due to an accidental headbutt that caused a major cut over Dawson's right eye and the fight was stopped by the ringside doctor.

Pascal defended his WBC light heavyweight title for the third time, won Dawson's IBO light heavyweight title, and filled the vacant Ring magazine light heavyweight title.
- August 28 – Giovanni Segura upsets Iván Calderón by a knockout in the eighth round to win the WBO and WBA super world light flyweight titles. Segura ends Calderón's undefeated 34-fight winning record. This fight would later be named both the best light flyweight and overall fight of the year of 2010 by Ring magazine.
- September 11 – Yuriorkis Gamboa defeats Orlando Salido to unified the WBA world and vacant IBF featherweight titles. Gamboa was knocked down in the eighth round and was docked two points in the twelfth round. While Salido was knocked down twice in the twelfth round.
- November 6 – Juan Manuel López defeats Rafael Márquez by TKO, in an exciting fight that was stopped early due to Márquez suffering a shoulder injury following the eighth round. López defends his WBO featherweight title and improves his record to 30–0. This fight is later named the best featherweight fight of 2010 by Ring magazine.
- November 13 – Manny Pacquiao destroys Antonio Margarito to the WBC super welterweight title, making Pacquiao the first and so far only boxer to win world titles in eight different weight classes.

This was Margarito's first major fight in over 21 months, following a knockout loss to Shane Mosley in January 2009.
- November 20 – In a highly anticipated rematch, Sergio Martínez knocks out Paul Williams in the second round to retain his WBC and Ring magazine middleweight titles. This fight was later named knockout of the year by Ring magazine.
- November 27 – Juan Manuel Márquez defeats Michael Katsidis by ninth-round TKO. Katsidis was competitive throughout the fight and even scored a knockdown on Márquez in the third round. While Márquez fought a more solid fight, landing many combinations. Márquez defends his WBO, WBA, and Ring magazine lightweight titles. This fight is later named the best lightweight fight of 2010 by Ring magazine.
- December 11 – Amir Khan defeats Marcos Maidana in a relatively close decision. Khan came out strong in the early part of the fight, by applying heavy pressure on Maidana and getting a knockdown late in the first round. However, in the later parts of the fight Khan spent much of his time avoiding Maidana trying to endure through rounds. At one point Maidana appeared to have almost finished Khan in the tenth round, when he landed a huge punch. However Khan absorbed the punishment and did enough in the early rounds to win by a unanimous decision. Khan defended his WBA world light welterweight title for the third time. This fight is later named the best light welterweight fight of 2010 by Ring magazine.
- December 11 – Abner Mares defeats Vic Darchinyan by a spit decision, to start Showtime's second boxing tournament based on the Super Six World Boxing Classic. However instead featured only four fighters, a single elimination format, and was focused on the bantamweight division at 118 lbs (54 kg) under the title, The Bantamweight Tournament: Winner Takes All. This fight was later named the best bantamweight fight of 2010 by Ring magazine.
- December 18 – After twelve rounds of boxing, Bernard Hopkins vs. Jean Pascal ends in a controversial majority draw.
- March 20 Milan–San Remo Óscar Freire wins first monument of the year over Tom Boonen in predicted sprint finish.
- April 4 Tour of Flanders Fabian Cancellara defeats home favourite Tom Boonen as 1 million people line the streets of Northern Belgium for the Unesco heritage race, famous for its culture, beautiful forests and brutal cobbled hills. Cancellara attacked first on the Molenberg with 44 km to go and Boonen was the only one who could follow. With 15 km to go Cancellara launched a powerful attack on the Muur-Kapelmuur using the last metres of the hill and descent to create a big gap. Once the gap was created, the world tt champion was always favourite and had time to celebrate.
- April 11 Paris–Roubaix Fabian Cancellara launched a surprising attack with over 45 km to go while Boonen was taking a drink behind. The Swiss, nicknamed Spartacus, showed incredible strength to stretch out the gap to over 4 minutes over the rest, before relaxing in the final kilometres to celebrate becoming one of the few people to achieve the Flanders Roubaix double in the same week.
- April 24 Liège–Bastogne–Liège Alexander Vinokourov came out victorious over Alexander Kolobnev with whom he worked to set up a 2-man finish. Vino attacked with 15 km to go, with many teams hesitant to bring him back, as drag Vinos teammate Alberto Contador, would then attack. With 9 km to go an elite group behind formed and home favourite Philippe Gilbert launched an all or nothing attack. Gilbert halved the 40 second deficit, but Vino and Kolobnev used their 2-man advantage to tire him out and ultimately contested the finish among themselves with Vino riding away to celebrate a successful comeback at the age of 36.
- May 8–30 Giro d'Italia Ivan Basso won what was considered to be one of the greatest Grand Tours of all time. With surprisingly exciting stages in the first week, including crashes in the Netherlands a ttt and a tough stage through the mud of Strade Bianchi, the race was blown apart on stage 12 when a group of 30 riders, including climbers David Arroyo and Carlos Sastre got a 12-minute lead. This forced the other contenders to push hard in the very difficult mountains of the 3rd week. Cadel Evans Michelle Scarponi Vincenzo Nibali and Basso took minutes over the leaders on 3 mountain stages, one of which was a mountain finish on the Monte Zoncolan, the hardest mountain in Grand Tour history, lined by hundreds of thousands of fans. The race came down to a difficult stage over the extremely difficult Passo di Mortirolo with a finish in Aprica. Basso needed 3 minutes to take the jersey from Arroyo, and looked likely to get it after taking 2 minutes on the ascent of the climb. But Arroyo surprised the world of cycling with an amazing descent of the mountain in very dangerous conditions, taking back 1 minute 30. The final twist came with the final climb into Aprica, were Basso, helped by teammate Nibali, and stage winner Scarponi, was able to take 3 minutes on Arroyo, gaining the jersey and a 2nd Giro win.
- July 3–25 Tour de France Alberto Contador won his 3rd Tour de France and 5th Grand Tour after a close duel with young Luxembourger Andy Schleck. The two were always comfortable, and close to each other, but the onus was on Schleck who was considered to be a far weaker time trial cyclist. Going into the stage on the Col du Tourmalet Schleck needed to get a gap over Contador, but, although he won the stage, Contador finished just behind Schleck and won the Tour on the time trial two days later.
- August 1–7 Tour de Pologne Dan Martin
- August 28–19 Vuelta a España Vincenzo Nibali won his first Grand Tour after putting in a surprisingly strong performance on the decisive stage. The strong favourite at the halfway point had been Igor Antón but the Euskaltel–Euskadi rider had an unfortunate crash and was forced to abandon. This left the Italian to fight it out with Galician climber Ezequiel Mosquera. Mosquera got time in several mountain stages, and needed 40 seconds on the final stage over the very steep Bola del Mundo. Huge crowds cheered on Mosquera as he attacked with 3 km and he was able to initially get 20 seconds. But Nibali came back and caught Mosquera in the last few metres, and though he was unable to overtake the Spaniard for the stage win, he was the overall winner.
- September 29–October 3 UCI Road World Championships Women's Time trial – Emma Pooley. Men's Time Trial – Fabian Cancellara. Women's Road Race – Giorgia Bronzini. Men's Road Race – Thor Hushovd won an epic race which looked to finish in anything but a sprint finish, until the last few kilometres. Several groups kept forming in attacks that looked likely to succeed, but ultimately always got brought back. Favourite Philippe Gilbert expected attack finally came on the 1st climb of the last lap. But as he was caught by a 2nd group, the peloton surprisingly appeared just behind them with 3 k to go and a sprint finish it turned out to be.
- October 17 Giro di Lombardia – Philippe Gilbert made up for his failure at the worlds with a 2nd victory in the final monument of the season. The Belgian was simply too strong throughout and never looked like losing. After a crash took out Nibali, Gilbert was left on his own, and waited for Michele Scarponi for support. But the Italian, who is superior in Grand Tours, was out of his depth contesting a one-day race against the classic specialist, who waltzed away with ease in the last few kilometres.
