Bio

Macy Chiasson (born July 27, 1991) is an American mixed martial artist (MMA). She was the Women's Featherweight winner of The Ultimate Fighter 28 and currently competes in the Bantamweight division in the Ultimate Fighting Championship (UFC). As of July 11, 2023, she is #9 in the UFC women's bantamweight rankings. Chiasson started mixed martial arts at the age of 19, after being bed-ridden for three and one-half weeks recovering from a car accident to get back the fitness level she once was when she was a softball player in high school. After attending some Krav Maga classes at the martial arts gym, she was attracted to the physical aggressiveness and the tough mental side of the combat sport and started teaching Krav Maga after one year of training. Chiasson transitioned to mixed martial arts, training under Mushin MMA and Mid City MMA, as Krav Maga is not a competition combat sport. Not long after she started training mixed martial arts, she started competing professionally.
