The Isuzu Cup, also known as the Isuzu Tournament, or the Isuzu Cup Tournament is an 8-man Muay Thai tournament which takes place at Siam Omnoi Stadium in Samut Sakhon every year. The tournament is organized by the Tri-Petch Group, owned by Isuzu,^[1] and sanctioned by the Sports Authority of Thailand.^[2] It is well-known as one of the best and the longest-standing tournament still active in the sport of Muay Thai.^[3]

The first Isuzu tournament started in late 1990. The final took place in early 1991 where Rattananoi Tansarinkhan won a decision over Weesanusak Wor.Weerakul.^[3]

In 2011, as the Tri-Petch Group became a sponsor of the new Thai Fight promotion, which aims for higher-weight talent, the tournament weight was raised to over 135 lbs for the first time. The winner of the Isuzu Cup, Kem Sitsongpeenong was entered into the second edition of the Thai Fight Tournament, which he ultimately won against Fabio Pinca, the winner of the first Thai Fight Tournament in 2010.

In 2012, the format was slightly changed as the winner of the Isuzu Tournament would have to participate in the Isuzu Cup Super Fight in order to qualify for the Thai Fight Tournament.^[4]

In 2023, the tournament was moved away from Siam Omnoi Stadium for the first time, as it was entirely fought in the Thai Fight promotion.

The Isuzu Cup Tournament is divided into three stages, starting with the Group Stage, in which the eight participants are divided into two groups accordingly called Group A and B. Each fighters has to fight all of the other members in his group and accumulate points before being able to move onto the next stage. The point system:

• 0 points for a loss
• 1 point for a draw
• 2 points for a decision win
• 3 points for a (technical) knockout win or decision win with a big cut on the opponent

The two fighters with the most points in each group will move on to the second stage, the Semi-finals, with the following match-ups:

• Group A winner vs Group B runner-up
• Group B winner vs Group A runner-up

The last stage is the tournament Final, which pits the winners of the Semi-finals against each other.

As of 2020:^[2]
