 Hailing from Olsztyn Poland, Joanna discovered Muay Thai when she was 16. Jędrzejczyk competed in Muay Thai and kickboxing for 10 years, winning over 60 national and international matches. Her amateur Muay Thai accomplishments include six IFMA World medals (five gold, one silver) and four IFMA European championships. During her professional career, Jędrzejczyk won five world titles including the WKN World Championship, J Girls Championship, WBKF Championship, WKF European Championship, and the WMC Championship. After transitioning to mixed martial arts and joining the UFC, Joanna quickly became one of the most dominant champions in the sport, capturing the women’s strawweight title, and defending it a record five times. She has fought in more title fights and accumulated more wins than any other woman in the division.
