10. James Irvin vs. Houston Alexander

Lasting just eight seconds, Irvin vs. Alexander went off at UFC Fight Night 13, as Irvin came out of the gates with a Superman punch that connected. Two more punches finished the job definitely. 

9. Makwan Amirkhani vs. Andy Ogle

This fight also lasted just eight seconds and came in Amirkhani’s UFC debut. Amirkhani also got in a few more licks while Ogle was on the ground, as Ogle scrambled as the fight as called. 

8. Leon Edwards vs. Seth Baczynski

Often criticized for his lack of knockouts, many forget Edwards knocked out Baczynski in just eight seconds via a haymaker of a right hand. Putting himself on the map, Edwards advanced to 9-2 with this win.

7. Don Frye vs. Thomas Ramirez

A true OG of the UFC, Fry knocked out Ramirez in just eight seconds at UFC 8. Frye also has one of the fastest submissions in the UFC and is a pioneer of the company. 

6. Ryan Jimmo vs. Anthony Perosh

This fight lasted just seven seconds, as Jimmo caught Perosh with a right hook that put him directly to sleep. Though the Canadian’s career wasn’t long in the UFC, this was certainly the highlight. 

5. Chan Sung Jung vs. Mark Hominick

The Korean Zombie knocked out Hominick in just seven seconds in 2011, as Hominick came out swinging wildly and paid dearly for it. Jung connected right away and pummelled him until the ref stopped it. 

4. Todd Duffee vs. Tim Hague

This heavyweight battle also lasted just seven seconds, as Duffee delivered a missile to Hague via his right hand that folded him at the knees. A few more extra punches certainly weren’t needed but happened nonetheless.

3. Terrance McKinney vs. Matt Frevola

McKinney made his UFC debut one to remember, knocking out Frevola in just seven seconds at UFC 263 just last year. 

2. Duane Ludwig vs. Jonathan Goulet

We’re now down to a six-second knockout, as Ludwig was scored initially with an 11-second knockout despite the UFC later admitting later it was just six. Either way, Goulet’s lights were out quickly despite the referee's error. 

1. Jorge Masvidal vs. Ben Askren

Fan-favorite Masvidal still holds the record for the fasted knockout in UFC history, needing just dive seconds to KO Ben Askren at UFC 239 a few years back. A flying knee was the weapon of choice, as Askren walked right into in what might go down forever as the fastest knockout in UFC history.
