A campervan (or camper van), sometimes referred to simply as a camper, and also known as a caravanette, motorhome or motorcaravan, is a self-propelled vehicle that provides both transport and sleeping accommodation. The term mainly describes vans that have been fitted out, often with a coachbuilt body for use as accommodation. In the United States the term "recreational vehicle" (RV) is more common for these vehicles, and in that country they tend to be larger than in Europe and the rest of the world.

Campervans may be equipped either with a "pop-up" roof which is raised during camping or a fixed roof, either shared with the commercial van that forms the basis of the vehicle (commonly a "high-top" model), or as part of a custom coachbuilt body.

Campervans usually have a small kitchen with a refrigerator (which is often powerable by a choice of gas, battery, or mains electricity) and a two-burner gas hob and grill. They generally have dual-voltage lighting which can work from either a dedicated battery (other than the van battery) known as a deep-cycle or leisure battery, or from AC power, supplied at a campsite via a hook-up cable. Larger models may include a water heater, space heating and air conditioning, a portable toilet and even an internal shower. Smaller models often carry a "porta-potty" portable toilet, and sometimes an external shower which operates within the privacy of an awning.

The term "Dormobile" is sometimes used generically in the United Kingdom thanks to a once highly popular conversion brand, and "Kombi" is used in Australia and other countries. The popularity of this type expanded in the 1950s after Volkswagen commissioned the Westfalia company to use the Kombi version of their Type 2 transporter as the basis for a campervan.
