Saroj Kumjit (; born March 3, 1962), known professionally as Jampatong Na Nontachai (), is a Thai former professional Muay Thai fighter. He is a former Rajadamnern Stadium Bantamweight Champion who was famous during the 1970s and 1980s. Nicknamed the "Master of Neck Kicks", he was especially known for his high kicks from both sides.
Jampatong was born in Ratchaburi Province, Thailand. He started Boxing at a young age as a means to help his family.
Early in his career, in June 1979, he gained two decision victories over Samart Payakaroon. In their third fight, due to Jampatong severely underperforming, the referee called a No contest.
In 1985, Jampatong won his first and last major title as he knocked out Sangtiennoi Sor.Rungroj with his signature high kick.
In 1986, he was a front runner for the Sports Writers Association of Thailand Fighter of the Year award but narrowly lost to Panomtuanlek Hapalang, the man who would take away Jampatong's Rajadamnern Stadium title later in that same year. In this year, he gained a shock upset win over Chamuekpet Hapalang as Jampatong knocked him out in the second round with his signature high kick.
Jampatong dove into a slump late in 1986 as he picked up losses against Jomwo Chuanyim, lost his Rajadamnern Stadium title to Panomtuanlek Hapalang.
In 1987, he suffered two of his worst defeats. In March, he was knocked out by a high kick against Suphaphet Kiatdipetnoi. In August, he was given another shot at the Rajadamnern Stadium title against former Lumpinee Stadium Champion, Yodpetch Sor.Chipattana. Jampatong was knocked out only 31 seconds into the fight.
Today, the former Yodmuay runs a noodle shop in Nonthaburi.
In June 2021, Sylvie von Duuglas-Ittu and her husband contacted Jampatong and filmed a long session with him for their Muay Thai Library at Jitmuangnon gym. It was the first time he had stepped into a ring in over 20 years.
