Haiphong

Hai Phong is a port city in northern Vietnam, about 120 kilometers east of Hanoi, one of the country's five centrally governed municipalities and, prior to a 2025 administrative merger, the third largest city in Vietnam by population with roughly 2.07 million residents recorded in 2021. Its harbor, the Port of Hai Phong, is the largest container port in northern Vietnam, anchoring extensive manufacturing, industrial and free-trade-zone development that has made the city one of the country's principal economic centers and marine distribution hubs.

Haiphong is the third-largest city in Vietnam, covering an area of about 3,195 square kilometers including the offshore islands of Bach Long Vi and Cat Ba in the Gulf of Tonkin. A major port city in the north of the country near Hanoi, Haiphong has long served as one of Vietnam's principal gateways for maritime trade and has grown in recent decades into a significant center for manufacturing and heavy industry.
