Da Nang or Danang is a class-1 municipality and the fifth-largest city in Vietnam by municipal population. It lies on the coast of the East Sea of Vietnam at the mouth of the Hàn River, and is one of Vietnam's most important port cities. As one of the country's five direct-controlled municipalities, it falls under the administration of the central government.
The city was known as Cửa Hàn during early Đại Việt settlement, and as Tourane during French colonial rule. Before 1997, the city was part of Quang Nam - Da Nang Province. On 1 January 1997, Da Nang was separated from Quảng Nam Province to become one of four centrally controlled municipalities in Vietnam.
