Chaung-U (Burmese: ချောင်းဦးမြို့) is a town in central Myanmar. It is located in Monywa District, Sagaing Division. It is the principal town of Chaung-U township. In the Bagan dynasty, when King Popa Saw Rahan (also known as King Taungthugyi) governed the country, it was named "San Tauk Village". It was a large village where different natives of the Union of Myanmar, like Kayin, Shan and Lawah (Wah) natives, lived happily together. Then, King Kyansit founded the city, gathering ten villages together, for example, Ywa Thit and Ywa Ma, naming it Chaung Oo (or Chaung-U). It is situated 231.46 feet (70.55 m) above sea level at north latitude 22° 45' and east longitude 95° 8' to 95° 25'. The Monywa–Mandalay highway road passes it, so the communication to it is good, quick and easy. The Monywa–Mandalay railway meets that of Chaung-U–Pakokku in the town's station, so you can get there by train. Its official township boundary touches the boundaries of other townships: Myinmu is in the east, Myaung is in the south and south-east, Salingyi is in the west, and Monywa is in the north.
