Read on to learn about the fastest knockout in UFC history. Explore the top 10 knockouts and some of the best fights in UFC history.

1. Jorge Masvidal vs. Ben Askren

Just four years ago, fans were treated to the fastest KO UFC history has to offer. It took just five seconds for Jorge Masvidal to defeat Ben Askren. No need for UFC judges to score this one.

As the fight started, Masvidal charged quickly at Askren. He jumped into the air with a flying knee. It connected with Askren’s face, sending him falling to the ground.

Masvidal pounced on his opponent, landing two more heavy blows to Askren’s face. At this point, however, the damage was already done. Askren was clearly unconscious after the initial knee to the head.

While other fights have come close, it seems unfathomable for this record to fall. For now, the record has stood for 4 years and running.

2. Duane Ludwig vs. Jonathan Goulet

Duane Ludwig came close to breaking the record for the fastest UFC knockout. For Ludwig, it took just six seconds to knock out his opponent, Jonathan Goulet.

Perhaps what makes this fight most impressive is that Ludwig needed only one punch. Goulet charged and attempted to throw his own punch. Ludwig successfully avoided it and connected it with a blow to the face.

Goulet dropped down to both knees and was unable to continue. What is interesting about this fight is that the official KO time is 11 seconds.

However, UFC President Dana White and other top officials have noted this was due to an official error. The actual KO time clearly occurred at the 6-second mark.

3. Todd Duffee vs. Tim Hague

You have to go back to UFC 102 for the next fastest KO. It took Todd Duffee just 7 seconds to knock out Tim Hague.

Hague took a big swing and missed with his left hand. Duffee capitalized and was able to put Hague on his back. Then, Duffee pounced and landed several huge blows to the head.

This was impressive speed for a heavyweight fighter. In total Duffee landed 9 strikes in this brief 7-second window.

4. Terrance McKinney vs. Matt Frevola

Terrance McKinney entered the UFC with a bang. In his debut, he was able to knock out Matt Frevola in seven seconds.

McKinney landed a combination strike at the start of the fight. He used his long reach to land a powerful left hand.

Next, he pounced and landed 5 consecutive right-handed clubs. This assault landed him on the list of best UFC knockouts.

5. Ryan Jimmo vs. Anthony Perosh

The outcome of this bout was never in question. From the start, Ryan Jimmo pushed forward with obvious confidence in his abilities.

On the other side, it appeared Anthony Perosh knew his fate as well. Immediately, he started backpedaling toward the cage.

Jimmo threw a ferocious right-hand hook. It landed clean right on the chin, leaving Perosh unconscious on the mat.

While Jimmo aggressively landed one more punch, it was not necessary as the fight was already over. In seven seconds, Jimmo was able to secure the third-fastest KO in UFC history.

6. Chan Sung Jung vs. Mark Hominick

Dubbed the “Korean Zombie,” Chan Sung Jung tied 4 other UFC fighters with a 7-second knockout. His came at the expense of Canadian fighter Mark Hominick.

Hominick aggressively went after Jung right from the start. The big mistake came with a huge miss with the left hand. Jung countered with a swift right-handed jab to the face.

Down went Hominick and Jung immediately seized his opportunity. He landed four more massive blows to Hominick’s face and the referee stopped the fight.

7. Don Frye vs. Thomas Ramirez

This knockout goes way back to the 1990s and UFC’s early years. At UFC 8, Don Frye took on Thomas Ramirez in a battle of two knockout artists.

The interesting thing about this fight is that Ramirez landed the first blow. Frye countered hard and landed a huge blow with his right hand.

Ramirez fell straight back to the mat and up against the cage. Frye attempted to continue his assault, but the referee intercepted him before more damage was done.

The end result was a Frye knockout in just 8 seconds. Frye is tied with a number of other UFC fighters for the fastest knockout.

8. Leon Edwards vs. Seth Baczynski

Seth Baczynski made a colossal mistake in this match. He went low with the right knee and Leon Edwards countered with a massive left-handed strike.

Baczynski fell to the mat and Edwards pounced. He delivered two more huge left-handed punches before the ref stopped it at the 8-second mark.

9. Makwan Amirkhani vs. Andy Ogle

This was a wild fight that also ended in 8 seconds. Makwan Amirkhani immediately charged Andy Ogle. He attempted a flying knee that Ogle was able to block.

However, this attack put him on the defensive. He backpedaled and tried to go low for Amirkani’s legs. Amirkhani delivered a powerful right-handed uppercut to end the fight promptly.

10. James Irvin vs. Houston Alexander

James Irvin has one of the coolest knockouts on this list. He faked out Houston Alexander with a right knee.
