The Saunders-Roe P.192 Queen was a British jet-powered seaplane project designed by Saunders-Roe after the Second World War. It was intended for the carriage of passengers on intercontinental flights, especially between Great Britain and Australia. No prototype was built because of a lack of funding.

The aircraft was designed to have flown at a cruising speed of 450 mph (720 km/h) and an altitude between 30,000 and 39,000 ft (9,000 and 12,000 m). Its range would have been 2,100 mi (3,400 km). The route between London and Sydney had already been planned, via Cairo, Karachi, Calcutta, Singapore and Darwin (Australia).
The fuselage would have had 5 decks with passengers divided into 6 person compartments with seats that could convert into berths for the night, in a similar fashion to railway carriages. First class passengers would have had their own bars, dining rooms and washrooms. A galley would have served all decks via freight elevator. The crew was to have consisted of 7 flight crews with their own rest quarters, and 40 cabin crew, as well as a steward as on a liner.

The engines were installed away from the hull to avoid spray ingestion on takeoff and landing. They were to have been supplied with air through intakes in the leading edge of the wing during flight, and another set of intakes on the top of the wing while on the water. Water rudders facilitated manoeuvring on the water.
