An Hoa Combat Base (also known as Duc Duc) is a former U.S. Marine Corps and Army of the Republic of Vietnam (ARVN) base west of Hội An in Quảng Nam Province, Vietnam.

The base was located approximately 28 km west of Hội An and 4 km west northwest of the Mỹ Sơn temple complex, near to the Tinh Yen River and the An Hoa industrial complex.

The base was first used by the Marines in January 1966 during Operation Mallard when the 1st Battalion, 12th Marines established a firebase there while the 1st Battalion, 3rd Marines and a Company from the 2nd Battalion, 9th Marines swept the surrounding area. On 20 April 1966 the Marines returned to An Hoa on Operation Georgia, the 12th Marines reestablished a firebase while the 3rd Battalion 9th Marines provided security, the base would become permanent at this time as the Marines sought to pacify the area. On 6 July 5 Marine Battalions launched Operation Macon around the An Hoa area, the operation continued into October resulting in 24 Marines and 380 Vietcong killed.

In August 1966 the Marines completed the construction of the "Liberty Road" between Danang and An Hoa.

An Hoa base was located southeast of a major Vietcong/People's Army of Vietnam base area known as the Arizona Territory across the Vu Gia River.

The airfield was capable of handling C-7, C-123 and C-130 aircraft.

Marine PFC Dan Bullock, the youngest American serviceman killed in action in the Vietnam War died at An Hoa on 7 June 1969.
