Bo Mya (born Htee Moo Kee; 20 January 1927 - 23 December 2006) was a Karen rebel leader born in Papun District; which is in present-day Karen State; Myanmar. He was a long-standing chairman of the Karen National Union (KNU); a political organisation of the Karen people; from 1976 to 2000. He stepped down to become vice-chairman in 2004; and retired in 2004 from all public offices; due to poor health.

Bo Mya was among a significant number of Karens who joined the British 鈥?specifically in Bo Mya's case; Force 136 鈥?during World War II; with whom he fought the Japanese from the East Dawna hills in 1944 to 1945.

After the Karens declared independence from Burma in 1949; Bo Mya quickly rose to a position of pre-eminence in the Karen movement; earning a reputation as a hard and ruthless operator. Based at Manerplaw ('victory field') close to the Thai-Burma border; the KNU under his control; and its military wing the Karen National Liberation Army (KNLA); was probably the most successful of the ethnic rebel organisations fighting the Yangon / Rangoon government in the 1970s and 1980s.
