Macy Chiasson

Macy Chiasson is an American mixed martial artist competing in the UFC women’s bantamweight division as of September 14, 2026. The UFC lists her as active, 5-foot-11, with a 72-inch reach, and identifies November 30, 2018, as her Octagon debut. Born July 27, 1991, Chiasson is from New Orleans, Louisiana. She studied Biological Sciences at the University of New Orleans before committing to a fighting career.

Chiasson turned professional in 2017 and emerged through The Ultimate Fighter 28, where she represented Team Gastelum. She won the women’s featherweight tournament at the November 30, 2018 finale by submitting Pannie Kianzad, earning a UFC contract. Although that breakthrough came at featherweight, she moved to bantamweight for her first post-tournament UFC bout and has competed primarily in that division during her UFC tenure.

A tall, long-range fighter for the division, Chiasson has shown a style that combines straight-punch and knee attacks in the clinch with effective positional grappling and submission work. Her UFC résumé includes stoppage victories by both strikes and rear-naked choke, reflecting a willingness to press opponents against the fence and pursue finishes rather than rely on a single discipline. Her most recently listed UFC appearance was against Ailin Perez on February 28, 2026.
