The MD Helicopters MD Explorer is a light twin-engined utility helicopter designed and initially produced by the American rotorcraft specialist McDonnell Douglas Helicopter Systems.

On 18 December 1992, the maiden flight was conducted, initial certification for the type followed roughly two years later. The initial model, the MD 900, was joined by an improved successor, the MD 902, during the late 1990s. The Explorer is currently produced by MD Helicopters.

The helicopter is noted for having no tail rotor, using the NOTAR technology instead, giving its tail a unique appearance and quieter sound profile than a more traditional tail rotor.
