Hải An is an urban district (quận) of Hai Phong, the third largest city of Vietnam.

Hai An hosts key transport connections across roads, waterways, rail, and air, with Lach Tray and Cam rivers surrounding the area and flowing into the Gulf of Tonkin via the Nam Trieu estuary.

The railway line from Lac Vien Station to Chua Ve Port also crosses the district.

Cat Bi International Airport, located in Hai An, has an annual capacity of 2 million passengers and nearly 12,000 tons of cargo.

This valuable infrastructure advantage positions the district as a strategic area for socio-economic development.
