Bien Hoa Air Base (Vietnamese: Sân bay Biên Hòa) is a Vietnam People's Air Force (VPAF) military airfield located in South-Central southern Vietnam about 25 km (16 miles) from Ho Chi Minh City, across the Dong Nai river in the northern ward of Tân Phong, and within the city of Biên Hòa within Đồng Nai Province. The boomburb city is densely populated and rings the base, despite significant levels of Agent Orange toxins simply left there for decades. Cleanup and remediation began in 2019.

During the Vietnam War the base was used by the Republic of Vietnam Air Force (RVNAF). The United States used it as a major base from 1961 through 1973, stationing Army, Air Force, Navy and Marine units there.
