As of July 2025, Stephen “Wonderboy” Thompson holds the distinction of being the oldest active fighter on the UFC roster. At 42 years old, the veteran welterweight continues to defy expectations in a sport that demands peak physical performance, lightning-fast reflexes, and intense endurance.
A Living Legend in the Octagon
Thompson, known for his elite karate-based striking and respectful demeanor, is preparing for his 22nd UFC fight — a testament to both his longevity and his relevance in the highly competitive welterweight division. His career has been marked by thrilling battles, including memorable clashes with Tyron Woodley, Jorge Masvidal, and Geoff Neal.
Despite his age, “Wonderboy” remains a fan favorite and continues to compete against top-tier opposition. His commitment to training, clean lifestyle, and tactical fight style have helped him avoid the kind of damage that ends many fighters’ careers early.
Outlasting His Peers
Thompson’s age places him ahead of other UFC veterans such as Jim Miller and Andrei Arlovski — both of whom are also over 40 and continue to fight. For years, lightweight Vinc Pichel held the title of the oldest active UFC fighter until his retirement, which paved the way for Thompson to claim that title.
Historically, the UFC has seen older fighters grace the Octagon, including Dan Severn, who was under contract at age 42, and legends like Mark Coleman, Anderson Silva, and Fabricio Werdum, who all competed in their 40s. However, few have done so at Thompson’s level of consistency and competitiveness.
The Secret to His Longevity
What sets Thompson apart is not just his age but how well he has maintained his athleticism. His background in traditional martial arts, particularly karate and kickboxing, emphasizes movement, timing, and distance management — key factors that have preserved his body through the years.
Additionally, Thompson has avoided the kind of brutal wars that shorten careers. His clean, technical style has allowed him to remain sharp and competitive without taking excessive damage.
A Legacy Still in Progress
As Thompson prepares for yet another Octagon appearance, he stands as a symbol of endurance and professionalism in mixed martial arts. His story proves that age is just a number when paired with discipline, experience, and an evolving approach to training.
Whether or not “Wonderboy” adds another title run to his legacy, he has already etched his name in the UFC history books — not just as a skilled martial artist, but now also as its oldest active fighter.
