Wa (Va) is an Austroasiatic language spoken by the Wa people of Myanmar and China. There are three distinct varieties, sometimes considered separate languages; their names in Ethnologue are Parauk, the majority and standard form; Vo and Awa, though all may be called Wa, Awa, Va, Vo. David Bradley (1994) estimates there are total of 820,000 Wa speakers.

The United Wa State Army, abbreviated as the UWSA or the UWS Army, is the military wing of the United Wa State Party (UWSP), the de facto ruling party of Wa State in Myanmar. It is a well-equipped ethnic minority army of an estimated 20,000–30,000 Wa soldiers, led by Bao Youxiang. The UWSA was formed after the collapse of the armed wing of the Communist Party of Burma (CPB) in 1989.
