Myanmar National Airlines (Burmese: မြန်မာအမျိုးသား လေကြောင်းလိုင်း), formerly Union of Burma Airways, Burma Airways, and Myanma Airways, is a state-owned airline and the flag carrier of Myanmar, based in Yangon. It operates scheduled services to all major domestic destinations and to regional destinations in Asia. Its main base is Yangon International Airport. Founded in 1948, it is one of the second oldest airlines in Asia after Malaysia Airlines.

The airline was founded by the government after independence on 15 September 1948, as the Union of Burma Airways (UBA). It initially operated domestic services only, and international services were added in 1950. The name was changed to Burma Airways in December 1972, and to Myanma Airways on 1 April 1989 following the renaming of the country from Burma to Myanmar. International services of Myanma Airways have been made as joint venture airline, Myanmar Airways International (MAI). Myanmar National Airlines is the majority shareholder of Joint Venture Company MAI, set up in 1993. In 2003, it was proposed to set up a Myanmar-based airline for chartered international passenger and cargo flights, which was planned to be called Air Myanmar. What would have been a joint-venture between Myanma Airways and private investors was abandoned in 2005.

In mid-2012, Myanma Airways ordered to lease two new Embraer 190AR from GE Civil Aviation Services Co.Ltd, that replaced its Fokker F-28 from November 2012. On February 11, 2014, at the Singapore Airshow, Myanma Airways signed a $960 million deal with GECAS for six Boeing 737-800s and four Boeing 737 MAX planes. The deal is the largest commercial sale by a U.S. company to Myanmar in decades and is the largest single aircraft order in the history of Myanmar's aviation industry.
