Naypyidaw (officially romanized Nay Pyi Taw and also spelled as Naypyitaw and Nay Pyi Daw) (Burmese: နေပြည်တော်; MLCTS: Nepranytau; pronounced [nèpjìdɔ̀] lit. 'Grand Capital'), is the capital and third-largest city of Myanmar. The city is located at the centre of the Naypyidaw Union Territory. It is unusual among Myanmar's cities in that it is an entirely planned city outside of any state or region. The city, then known only as Pyinmana District, officially replaced Yangon as the administrative capital of Myanmar on 6 November 2005; its official name was revealed to the public on Armed Forces Day, 27 March 2006.

As the seat of the government of Myanmar, Naypyidaw is the site of the Union Parliament, the Supreme Court, the Presidential Palace, the official residences of the Cabinet of Myanmar and the headquarters of government ministries and military. Naypyidaw is notable for its unusual combination of large size and very low population density. The city hosted the 24th and 25th ASEAN Summit, the 3rd BIMSTEC Summit, the Ninth East Asia Summit, the 2013 Southeast Asian Games and the 2014 AFC U-19 Championship.
