This article is about the Vietnamese city. For the puzzle game, see Tower of Hanoi.

Hanoi (Vietnamese: Hà Nội; Chinese: 河内), estimated population 3,500,800 (1997), is the capital of Vietnam and was the capital of North Vietnam from 1954 to 1976. The city is located on the right bank of the Red River. Manufactures include machine tools, plywood, textiles, chemicals, and handicrafts.

Hanoi became the capital of Vietnam in the 7th century. Its Chinese-derived name, Đông Kinh, became Tonkin and was applied by Europeans to the entire region. Hanoi was occupied by the French in 1873 and passed to them ten years later. It became the capital of French Indochina after 1887.

The city was occupied by the Japanese in 1940, and liberated in 1945, when it became the seat of Vietnam's government. From 1946 to 1954, it was the scene of heavy fighting between the French and Viet Minh forces. At that point, the city became the capital of an independent North Vietnam.

During the Vietnam War Hanoi's transportation facilities were disrupted by the bombing of bridges and railways, which were, however, immediately repaired. Following the end of the war, Hanoi became the capital of all Vietnam when North and South Vietnam were united on July 2, 1976.

In the city are the National University of Vietnam (formerly Hanoi University ), Ho Chi Minh mausoleum, the National History Museum, the Revolution Museum, and several historic monuments. The National Museum of Fine Art is also located in Hanoi.
