A dune buggy — also known as a beach buggy — is a recreational off-road vehicle with large wheels, and wide tires, designed for use on sand dunes, beaches, off-road or desert recreation. The design is usually a topless vehicle with a rear-mounted engine. A dune buggy can be created by modifying an existing vehicle or custom-building a new vehicle.

An off-road vehicle (ORV), sometimes referred to as an off-highway vehicle (OHV), overland vehicle, or adventure vehicle, is considered to be any type of vehicle that is capable of driving off paved or gravel surfaces, such as trails and forest roads that have rough and low traction surfaces.
