Knockouts usually belong to the young in UFC and MMA, the fast-twitch athletes who rely on speed and explosiveness. But every now and then, a veteran flips that narrative on its head. In the UFC, a handful of fighters have carried their power deep into their 40s, proving that timing, experience, and composure can be just as lethal as youth.
Who are the oldest UFC fighters to secure a knockout victory?
Dan Henderson 46 years, 2 months
Dan Henderson produced one of the most memorable late-career finishes when he knocked out Hector Lombard at UFC 199. He was behind on the scorecards, absorbing damage, and then in a split second, everything changed. One clean right hand, his trademark shot, and the fight was over. Moments like that are why his power was feared for decades.
Mark Hunt 42 years, 5 months
Mark Hunt didn’t rely on volume, he only needed one. Against Derrick Lewis, he delivered exactly that, landing a perfectly timed punch that shut the lights out. Even late in his career, Hunt’s ability to read exchanges and land clean made him a constant danger.
Andrei Arlovski 42 years, 1 month
Andrei Arlovski has had one of the longest runs in heavyweight history, and his knockout win over Philipe Lins showed how much craft matters. It wasn’t wild or reckless, it was measured, patient, and precise, the kind of finish that comes from years inside the cage.
Aleksei Oleinik 43 years, 3 months
Aleksei Oleinik built his reputation on submissions, which made his knockout win at this stage of his career even more surprising. It wasn’t something people expected, but it spoke to his adaptability and willingness to evolve, even after decades in the sport.

Randy Couture 43 years, 1 month
Randy Couture returning to win and then stop Tim Sylvia felt almost unreal at the time. He wasn’t supposed to win, let alone dominate. But through positioning, control, and relentless pressure, he broke down a much younger champion and reminded everyone why experience can’t be underestimated.
There’s something different about knockouts like these. They’re not just about power, they’re about knowing when to use it. These fighters didn’t just last longer than most, they found ways to remain dangerous, turning every exchange into a potential turning point no matter their age.
