5. Michael Johnson’s explosive UFC debut knockout (July 7, 2017)

This moment introduced fans to the chaos he would consistently cause.

4. Brutal head-kick KO of Dustin Poirier for the BMF title (July 29, 2023, UFC 291)

In a highly anticipated rematch, Gaethje avenges his 2018 loss to Dustin Poirier in spectacular fashion. After a measured first round, he landed a perfect head kick early in the second, rocking Poirier before swarming to the TKO. The win captured the symbolic BMF (“Baddest Motherf***er”) title and earned Performance of the Night. It was a statement of redemption and violence, proving that Gaethje could adapt and end elite opposition.

This knockout is often repeated as one of his cleanest and most satisfying finishes.

3. Winning the interim lightweight title against Tony Ferguson (May 9, 2020, UFC 249)

In the first UFC event of the COVID era, Justin Gaethje stepped in on short notice and delivered a five-round masterclass against undefeated Tony Ferguson. He defeated and defeated “El Cucuy” and finished with a fifth-round TKO to claim the interim UFC Lightweight Championship. The performance earned Fight of the Night and Performance of the Night, halting Ferguson’s twelve-fight win streak and positioning Gaethje as a true title contender.

It remains one of his most complete and dominant displays.

2. The Epic War with Michael Chandler (November 6, 2021, UFC 268)

Few fights reflect Gaethje’s style as much as his bloody brawl with Michael Chandler at Madison Square Garden. Both men traded bombs over three rounds in a non-stop action fight that lived up to the hype. Gaethje earned a unanimous decision victory and earned Fight of the Night. Many media outlets named it Fight of the Year, highlighting his heart, chin and ability to thrive in pure chaos.

This fight cemented his reputation as the epitome of violence in MMA.

1. Max Holloway’s iconic last-second knockout loss (April 13, 2024, UFC 300)

Although it is a loss, this moment is Gaethje’s most unforgettable because of the drama. Gaethje defended the BMF title against Max Holloway and waged a war of attrition for five rounds. In the final 10 seconds of the fight, Holloway landed a devastating right hook that knocked out Gaethje and won the BMF title in one of the most shocking and cinematic finishes in UFC history. Gaethje earned Fight of the Night for his efforts.

The image of that knockout – and Gaethje’s warrior performance throughout – has become legendary and, despite the result, is often cited as a defining highlight of his career.

Honorable mentions include his first-round destruction of Edson Barboza (2019), the brutal war with Eddie Alvarez (2017) and his recent gritty interim title win over Paddy Pimblett (January 24, 2026, UFC 324), which added a new chapter to his highlight-reel resume.
Gaethje’s moments aren’t just about victories; they’re about entertainment, heart and delivering fights that fans will remember forever.

“The Highlight” continues to live up to its name.
