Somphop Kamnil (; born May 6, 1968 â 2001), known professionally as Jaroensak Kiatnakornchon (), was a Thai former professional Muay Thai fighter. He was a Lumpinee Stadium and Rajadamnern Stadium champion at Bantamweight who was active during the 1980s and 1990s.
He trained at the Kiatnakornchon gym and was known for his technical southpaw kicking style.
The peak of his career was during the Golden Era of Muay Thai against Samson Isaan, Saenklai Sit Kru Od, Yodkhunpon Sittraiphum, and Veeraphol Sahaprom whoâÂÂre considered amongst the greatest fighters of all time. Most notably he defeated Samson by decision for his Bantamweight title at Lumpinee Stadium, won another decision against Samson, lost another decision to Saenklai, defeated Yodkhunpon by decision, lost the final fight against Samson by third-round knockout, and then lost his title to Yodkhunpon in 1992.

Sometime after his retirement, he was stabbed and killed in an altercation.
