Đà Nẵng Port (Vietnamese: Cảng Đà Nẵng) is a major port system located in Central Vietnam at the mouth of the Han River on the South China Sea, in the city of Đà Nẵng. It is the third largest port system in Vietnam (after Saigon Port in Hồ Chí Minh City and the port of Hải Phòng). Đà Nẵng Port lies at one end of the East–West Economic Corridor, an economic corridor connecting Vietnam with Laos, Thailand, and Burma. Vietnam National Shipping Lines (Vinalines) is the port's authority.
In 2008, Đà Nẵng Port handled 2.7 million tons of cargo, of which 1.2 million tons were exports, 525,900 tons were imports, and 985,600 tons were domestic cargo. Over 29,600 passengers passed through the port in 2008, a significant increase over previous years. Despite the fact that the port's infrastructure is not specifically designed to accommodate cruise ships, the number of large cruise ships docking at Đà Nẵng Port has increased in recent years. In the first two months of 2010 alone, 12 cruise ships docked in Đà Nẵng, carrying 6,477 passengers.
Đà Nẵng has been a port city for many centuries, long before the first arrival of European traders in the 16th century. One of the first Europeans to visit the city was Portuguese explorer Antonio De Faria, who anchored at Đà Nẵng Port in 1535. De Faria was one of the first Westerners to write about the area, and through his influence Portuguese ships began to call regularly at Hội An, which was then a far more important port than Đà Nẵng.
Throughout the 17th and 18th centuries, French and Spanish traders and missionaries regularly made landfall at Hội An, just south of Đà Nẵng. In 1787, Emperor Gia Long concluded a treaty with King Louis XVI, whereby he ceded Đà Nẵng Port to the French in return for promised military aid.
