Map - Quang Nam province (Tỉnh Quảng Nam)

Quảng Nam is a province in the Central region of Vietnam. It is bordered by Thừa Thiên–Huế province to the north, the nation of Laos to the west, Kon Tum province to the southwest, Quảng Ngãi province to the southeast, the South China Sea to the east, and the city of Da Nang to the northeast. The province is known for being a tourist destination in the Hội An cultural site, alongside an export and manufacturing hub within central Vietnam.

Human habitation in the province has been continuous for 2,200 years, starting with the Sa Huỳnh culture.

Quảng Nam was once the political and near the geographic centre of Champa and the province was gifted in 1307 in exchange for a marriage to a Vietnamese princess. For some time both the most powerful city-state and the busiest Cham port (at Hội An) were located in what is now Quảng Nam. Trade in luxury goods from the Central Highlands was the basis of this wealth and power. As a result of warfare with Vietnam, the centre of political power of the Cham shifted south to Vijaya. The trade in luxuries continued for some time under the Nguyễn lords but declined gradually, especially under the Nguyễn dynasty and further in colonial Vietnam, when the economic focus shifted to the agriculture of the large river deltas.

As the site contained several mountain passes, it has historically been a center for conflict between ruling powers and dynastic struggles. The site was the scene of heavy inter-dynastic fighting between the Trịnh–Nguyễn War and the point in which the Nguyen dynasty had escaped following their expulsion from their strongholds in the north. Its primary city of Hội An was destroyed and rebuilt during the Tay Son rebellion.

The province of Quang Nam has historically served as a trade site and was a major port region in Southeast Asia for trading high-grade silk, fabrics, paper, porcelain, areca nuts, pepper, Chinese medicines, elephant tusks, beeswax, mother-of-pearl and lacquer. The Dutch brought Vietnamese slaves they captured from Nguyễn lord territories in Quảng Nam province to their colony in Taiwan.

As a trade hub, Quang Nam would also serve as the site where Western influence would enter into Vietnam. Notably Alexandre de Rhodes who had written the alphabet, and also where a military alliance with France was signed between Nguyen dynasty monarchs fleeing the Tay Son Rebellion. The region would also see the start of French colonization during Cochinchina campaign and the Siege of Tourane.

The province was split into two in 1962, with the southern half known as Quảng Tín province. The province was also the site of heavy fighting during the Vietnam War, until it was captured in the Hue–Da Nang Campaign. The two provinces were merged again after unification in 1976. In 1997 its former capital city of Da Nang was separated into its own administrative entity.
