Hardest punch ever landed

Mugabi's uppercut to Hagler in the 6th rd would've layed out for the full 10 count most Jr.Middle/ middleweights in history.
I also believe after he landed that shot, and Hagler was still their ( Even more pissed off) standing, Mugabi became discouraged, knowing even he couldn't hit this man hard enough to seriously hurt him.
Also , Arguello turning Aaron Pryor's head into a scene from the movie the Excorcist . Arguello hit Pryor so hard and clean, it looked like Pryor's chin was over his shoulder for a second.
Holmes hitting Tex Cobb for 15rds like a punching bag. Cobb was hit so hard and often Howard Cosell had a melt down because the fight wasn't stopped , he said he'd never announced another boxing match . ( I don't believe he ever did)

 

Fury's comeback from the dead. How that was not a knockout and he got up from that I dont know.

 

Marciano and Charles' first fight there were no knockdowns and it went 15, towards the end of 15 at some point Charles fades a bit and stops answering back and isn't putting up much defense, Marciano goes all out trying to finish him and lands a couple uppercuts and some really heavy left hooks with some follow up rights, one of which looked to land directly to the ear, Charles definitely has one of the greatest chins of all time

 

In my opinion, the hardest punch ever landed that did not result in a knockdown was landed on me while sparring in 1987, or maybe 85. I was leaning forward inside and got hit with an uppercut on the nose. To this day, when I breathe through my nose it sounds like an alligator eating a pig under water and, if I think about it for too long, I still see stars.

 

my vote
@greynotsoold .. Is he getting more leverage here than any and/or ( most ) over hand rights that can be thrown?

You can get a lot of leverage on a left hook- it has always been my favorite, and best, punch.
In the Walcott v Charles video, it is pretty apparent that Walcott knew that Charles was going to jab as soon as he stepped into range. Charles did, and Walcott slipped the punch. When he slipped the punch Walcott did 2 things. First, he got he weight over his left leg. Second, he brought his right foot forward. That second thing is really important because, to really get leverage on a hook, you have to shift the weight to the right foot and that is hard to do if you don't bring the right foot forward when you step in. Walcott didn't get the weight all the way onto his right foot but he got his hips turned through the punch.
In the Robinson v Fullmer clip, this is another example of Robinson knowing what was going to happen before it did. This is a short clip, but, I believe, Robinson jabbed 3 times and Fullmer used his left arm to block the jab and threw a right hand to the body. For the ko, Robinson gave him a jab look as he stepped back; when he stepped back all the weight went to his right foot and Robinson turned over the weight. Then you add in that Fullmer was turning his weight on the right hand, he got hit really hard.
You can generate a lot of torque on a hook, and- especially if your are good at setting it up- it comes from angles and the target doesn't see it coming.

 

Tony DeMarco landed a left hook on Carmen Basilio in the 7th round of their rematch and Basilio performed the Judah dance, but refused to go down. He took a lot, he messed around a lot, but he made it to the end of the round and cleared the cobwebs between rounds.

 

You might have to add "that did not result with a knockdown?" to the initial thread title next time as we can be a bit slow in here, myself included at times

We've got near as many answers that were the complete opposite as those you asked for.

 

Yes, & I suggest adding "pound for pound" or "for their division".
Because almost certainly the hardest punch ever landed in any context was by someone over 200 lbs. in the ring.

And almost no possibility it would be thrown by someone under the 180's.

 

One of the first fights I ever watched. I was a K2 fan because of the Drago aesthetic in my head- brutal. I remember jokingly telling my cousin “throw in the damn towel”

 

Lennox Lewis hit Mavrovic with a 3 piece combo from hell at the end of R7, while having a 30 pound weight advantage, and Mavrovic ate it.

 

James Thunder vs Crawford Grimsley.

 

This left hook from Holyfield at 5:16 of the video.. How did Savarese get up from that?

The right from Cuevas which fractured the eye socket of Billy Backus, ending the former World Welterweight Champion's career. Backus did go down later, got up, but his career was over. Pipino, like many sluggers, was an intelligent fighter. He winged huge definitively leveraged rights directly at southpaw Backus.

Pipino lands the career ender on Billy at 2:22...:
