The McDonnell F2H Banshee (internally, the McDonnell Model 24) was a single-seat carrier-based jet fighter aircraft deployed by the United States Navy and United States Marine Corps from 1948 to 1961. It was one of the primary American fighters used during the Korean War and was the only jet-powered fighter deployed by the Royal Canadian Navy. The aircraft's name is derived from the banshee of Irish mythology.

The new aircraft would use much larger and more powerful engines, a pair of newly developed Westinghouse J34 turbojets, nearly doubling the total thrust from 3,200 to 6,000 lbf (14,000 to 27,000 N) compared to the FH Phantom but since the larger engines still had to fit within the wing roots, this required a larger and thicker wing. The more powerful engines used more fuel, so the fuselage had to be enlarged and strengthened to increase the fuel capacity. The Navy was replacing the obsolete World War II .50 in (12.7 mm) machine guns with 20 mm (0.79 in) cannon, four of which were mounted under the nose where pilots would not be blinded by muzzle flash when firing at night, a problem with the FH Phantom. The Banshee incorporated an ejection seat, which the FH Phantom lacked, and a large number of improvements to other aircraft systems. The cockpit was pressurized and air-conditioned, and the flaps, landing gear, folding wings, canopy, and air brakes were electrically rather than pneumatically operated. The front of the windscreen was bulletproof glass that was electrically heated to prevent frost.
