RFA Argus is a ship of the Royal Fleet Auxiliary, part of the Royal Navy. Italian-built, Argus was formerly the container ship MV Contender Bezant. The ship was requisitioned in 1982 for service in the Falklands War and purchased outright in 1984 for use as an Aviation Training Ship, replacing RFA Engadine. In 1991, during the Gulf War, she was fitted with an extensive and fully functional hospital to assume the additional role of Primary Casualty Receiving Ship. In 2009, the PCRS role became the ship's primary function.

As the ship is armed, the Geneva Convention prevents it from being officially classified as a hospital ship.
