HMAS Aitape (P 84) was an Attack class patrol boat of the Royal Australian Navy (RAN). It was named for the small town of Aitape, Sandaun Province, Papua New Guinea. Completed in 1967, 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 Aitape. She remained active until 1982, when she was removed from service for use as a parts hulk. Aitape was scuttled off Port Moresby for use as a dive wreck in 1995.

The Attack class was ordered in 1964 to operate in Australian waters as patrol boats (based on lessons learned through using the Ton class minesweepers on patrols of Borneo during the Indonesia-Malaysia Confrontation), and to replace a variety of old patrol, search-and-rescue, and general-purpose craft. Initially, fourteen were ordered for the RAN, five of which were intended for the Papua New Guinea Division of the RAN, although another six ships were ordered to bring the class to twenty vessels.

The patrol boats had a displacement of 100 tons at standard load and 146 tons at full load, were 107.6 feet (32.8 m) in length overall, had a beam of 20 feet (6.1 m), and draughts of 6.4 feet (2.0 m) at standard load, and 7.3 feet (2.2 m) at full load. Propulsion machinery consisted of two 16-cylinder Paxman YJCM diesel engines, which supplied 3,460 shaft horsepower (2,580 kW) to the two propellers. The vessels could achieve a top speed of 24 knots (44 km/h; 28 mph), and had a range of 1,200 nautical miles (2,200 km; 1,400 mi) at 13 knots (24 km/h; 15 mph). The ship's company consisted of three officers and sixteen sailors. Main armament was a bow-mounted Bofors 40 mm gun, supplemented by two .50 calibre M2 Browning machine guns and various small arms. The ships were designed with as many commercial components as possible: the Attacks were to operate in remote regions of Australia and New Guinea, and a town's hardware store would be more accessible than home base in a mechanical emergency.
