The Hughes H-1 is a racing aircraft built by Hughes Aircraft in 1935. It set a world airspeed record and a transcontinental speed record across the United States. The H-1 Racer was the last aircraft built by a private individual to set the world speed record; most aircraft to hold the honor since have been military designs.

Streamlining was a paramount design criterion resulting in one of the cleanest and most elegant aircraft designs ever built. Many groundbreaking technologies were developed during the construction process, including individually machined flush rivets that left the aluminium skin of the aircraft completely smooth. The H-1 also had retractable landing gear to further increase the speed of the aircraft, including a fully retractable hydraulically actuated tail skid. It was fitted with a Pratt & Whitney R-1535 twin-row 14-cylinder radial engine of 1,535 cubic inches (25.15 l), which although originally rated at 700 horsepower (522 kW), was tuned to put out over 1,000 horsepower (750 kW).

Due to two different roles being envisioned for the racing aircraft, a set of short-span wings for air racing and speed records and a set of long wings for cross-country racing were prepared.
