Hsinbyushin (, , ; ; 12 September 1736 – 10 June 1776) was king of the Konbaung dynasty of Burma (Myanmar) from 1763 to 1776. The second son of the dynasty founder Alaungpaya is best known for his wars with China and Siam, and is considered the most militaristic king of the dynasty. His successful defense against four Chinese invasions preserved Burmese independence. His invasion of Siam (1765–1767) ended Siam's Ayutthaya Dynasty. The near simultaneous victories over China and Siam has been referred to as testimony "to a truly astonishing elan unmatched since Bayinnaung." He also raised the Shwedagon Pagoda to its current height in April 1775.
