Phú Quốc

Phú Quốc (Vietnamese: [fǔ wuə̌k]) is the largest island in Vietnam. Previously organized as Phú Quốc City (which also combined nearby islands and the distant Thổ Chu Islands), it was Vietnam's first island municipality. The island has a total area of 575 km² (222 sq mi) and a permanent population of approximately 179,480 people in 2020. On June 16, 2025, Phú Quốc became one of the 13 newly established and re-organized special administrative zones of Vietnam, the only city to do so. Later on July 1, "Secretary of the City Committee" Lê Quốc Anh was appointed to become the first "Secretary of the Party Committee of the special zone".

Located in the Gulf of Thailand, Phú Quốc special administrative zone includes the island proper and 21 smaller islets. Dương Đông ward, located on the island's west coast, is the island's administrative centre and largest town. The other ward is An Thới on the southern tip of the island.

Its primary industries are fishing, agriculture, and a fast-growing tourism sector. Phú Quốc has achieved fast economic growth due to its current tourism boom. Many infrastructure projects have been carried out, including several five-star hotels and resorts. Phú Quốc International Airport is the hub connecting Phú Quốc with mainland Vietnam as well as with international destinations.

Since March 2014, Vietnam has allowed all foreign tourists to visit Phú Quốc visa-free for a period of up to 30 days. By 2017, the government of Vietnam planned to set up a Special Administrative Region which covered Phú Quốc Island and its peripheral islets and upgrade it to a provincial city with special administration.

The historical Phú Quốc Prison was based here, the prison was built by the French to detain captured Viet Minh fighters. Continuing into the Vietnam War, Viet Cong and North Vietnamese Army POWs were monitored by South Vietnamese soldiers.
