Aung La Nsang

Aung La Maung Nsang (; born on May 21, 1985) is a Burmese and American professional mixed martial artist. He competed in both the middleweight and light heavyweight divisions of ONE Championship, where he is a former ONE Middleweight and ONE Light Heavyweight World Champion, and was the second two-division champion in ONE history, having held both belts simultaneously.

He made his MMA debut in 2005 and would go on to become a major star in his native Myanmar after signing with ONE Championship and winning two titles with the organization. Aung La Nsang is a national icon in Myanmar and a bronze statue of him was erected in 2018 at the Kachin National Manau Park in his hometown of Myitkyina. During the opening ceremony of the statue, a huge crowd of thousands fans gathered. Aung La Nsang is one of the few Myanmar citizens with an international profile, given the country only began opening up to the outside world over the last decade. He was the subject of unprecedented national attention in the lead-up to the fight with Russia's then-middleweight champion Vitaly Bigdash, with billboards across Yangon featuring massive portraits of the two fighters.

Early life, education and religion Aung La was born in Myitkyina, Kachin State, Myanmar to Christian Kachin parents Nsang Tu Awng, a jewellery trader, and his wife Shadan Nang Bu. He is the third son of five siblings. He attended high school at International School Yangon.

Aung La Nsang said he got his nickname of the "Burmese Python" while fighting in the Midwest. A promoter from the Midwest asked where he was from and didn't know where Burma was. Aung La Nsang told him Burma was where the Burmese Python is from and so the promoter started to call him that. The geo-political sensitivities was not aware to the promoter.

Aung La Nsang is a devoted Christian whose faith in God developed during his childhood. On 3 May 2026, he took part in a religious discussion with The Orthodox Muslim Youtube Channel as a layperson. During the discussion, he shared and explained his Christian beliefs and faith.

Aung La Nsang said, "Of course the Kachin people want me to become the Kachin Python or the Kachin Lion, but you can't give yourself a nickname ... It just comes from the fans."

Lethwei

Aung La Nsang has no formal training in his home country's traditional art of Lethwei and only fought with his cousins and friends. He said his uncle used to fight in Lethwei, but his experience was limited. He lists Tway Ma Shaung as one of his favorite Lethwei fighters alongside Lone Chaw. Aung La has often expressed his interest in Lethwei, and stated being open to a mixed-rules MMA-Lethwei fight, which could happen as ONE Championship already held Lethwei fights, notably at ONE Championship: Light of a Nation.

Mixed martial arts career Early career Aung La made his professional debut in 2005, and soon built a reputation for his outstanding submission skills, earning himself the nickname of The Burmese Python. Early in his career, Aung La fought for King of the Cage and Ring of Combat as well as other, smaller promotions. However, his career got off to a slow start, with Aung La losing his first fight. At the age of 27, he became a social media sensation when footage of him knocking out Jason Louck at CFFC 17 went viral in the Kachin State. After the fight, he posed with a Kachin flag.

ONE Championship He made his ONE Championship debut in June 2014 and has headlined multiple shows at the Thuwunna Stadium in Yangon since 2016. After signing with ONE in 2014, Aung La Nsang returned to his home country of Myanmar two years later at ONE Championship: Union of Warriors, winning his bout to become a national hero.
