About Marie McManamon

Marie McManamon is a distinguished Muay Thai fighter hailing from the United Kingdom, currently training and competing out of Knowlesy Academy in London, England.

This is the same gym that has bred fighters like former two-division ONE Muay Thai World Champion and current ONE Bantamweight Kickboxing World Champion Jonathan Haggerty and fast-rising star Freddie Haggerty.

Throughout her career, McManamon has established herself as one of the U.K.’s premier female Muay Thai athletes. A relentless force in the ring, she has used her unstoppable cardio and whipping kicks to earn both Victory League and Roar Fighting Championship Titles.

Her dominance in the local Muay Thai circuit caught the attention of ONE Championship in 2025. Now part of the world’s largest martial arts organization, McManamon has one goal in mind — to win the ONE Women’s Atomweight Muay Thai World Title.
