Martyna Kierczynska

Martyna Kierczynska joined the world’s largest martial arts organization with a sole purpose – to win the ONE Women’s Atomweight Muay Thai World Title.

The Polish fighter began her journey to ONE Championship by dominating the local European Muay Thai scene. In fact, in 2023, Kierczynska’s skills secured her a WMC Muay Thai World Championship.

She made her ONE debut shortly thereafter, making a strong showing for herself at ONE Fight Night 19. There, she scored a second-round technical knockout of Nat “Wondergirl” Jaroonsak with a barrage of punches, elbows, and knees.

Although she faced a temporary roadblock to the World Title in her next fight, Kierczynska is always ready and willing to throw down with the best the division has to offer.
