HMAS Madang (P 94), named for the settlement of Madang in New Guinea, was an Attack class patrol boat of the Royal Australian Navy (RAN). Completed in 1968, the vessel was one of five assigned to the RAN's Papua New Guinea (PNG) Division. The patrol boat was transferred to the Papua New Guinea Defence Force in 1974 as HMPNGS Madang. She was decommissioned in 1989.
