The Bell UH-1 Iroquois "Huey" is a utility military helicopter designed and produced by the American aerospace company Bell Helicopter. It is the first member of the prolific Huey family, as well as the first turbine-powered helicopter in service with the United States military.

Development of the Iroquois started in the early 1950s, a major impetus being a requirement issued by the United States Army for a new medical evacuation and utility helicopter. An initial production contract for 100 HU-1As was issued in March 1960. In response to criticisms over the rotorcraft's power, Bell quickly developed multiple models furnished with more powerful engine.

The Iroquois was first used in combat operations during the Vietnam War, the first examples being deployed in March 1962. It was used for various purposes, including conducting general support, air assault, cargo transport, aeromedical evacuation, search and rescue, electronic warfare, and ground attack missions. Armed Iroquois gunships carried a variety of weapons, including rockets, grenade launchers, and machine guns, and were often modified in the field to suit specific operations. The United States Air Force deployed its Iroquois to Vietnam, using them to conduct reconnaissance operations, psychological warfare, and other support roles.

The Iroquois was originally designated HU-1, hence the Huey nickname, which has remained in common use, despite the official redesignation to UH-1 in 1962.

Bell Helicopters was the winner of a 1963 United States Air Force competition for a support helicopter for use on its missile bases. The resulting UH-1F had the shorter cabin of the "Bravo" Huey, but with a longer tail boom, rotor and transmission. The iconic aircraft of the Vietnam War with the distinctive "wop-wop" of the Huey's rotor blades stirs the memories of the generation that came of age during the turbulent 1960s.

The UH-1F was introduced into the USAF inventory in February 1964. The USAF took delivery of 119 Huey with production ending in 1967. Many of the aircraft served in southeast Asia with the 20th Special Operations Squadron and some were converted to the armed UH-1P configuration.
