Yothin Hamuthai (; born February 22, 1992), known professionally as Yothin F.A.Group (), the “King of Muay Khao”, is a Thai Muay Thai fighter. He is the current Rajadamnern Stadium Featherweight Champion.
Biography and career
Yothin started fighting at 5 years old and was training in his hometown before joining the Sakaethongresort gym in the Isan region until he was scouted by FA Group gym.
Yothin has modeled his career on that of a knee fighter from the same gym Petchboonchu FA Group under the same teacher Kru Diesel.
From March 2016 to March 2017 Yothin had 8 victories and only 1 defeat which led him to be on the shortlist for the Thailand Sports Writers Fighter of the Year Award. This extended winning streak in the Rajadamnern Stadium got Yothin to be ranked #1 in the stadium rankings in his division.
After becoming the 2024 WBC Muay Thai International Featherweight (126 lbs) Champion, Yothin became the 2024 Rajadamnern Stadium Featherweight (126 lbs) Champion. He successfully defended his Rajadamnern title in May 2025.
