A sport utility vehicle (SUV) is a generic marketing term for a vehicle similar to a station wagon, but built on a light-truck chassis. Usually equipped with four-wheel drive for on or off-road ability, some SUVs include the towing capacity of a pickup truck with the passenger-carrying space of a minivan. Since SUVs are considered light trucks and often share the same platforms of pick-ups, they are regulated less strictly than passenger cars under the two laws in the U.S., the Energy Policy and Conservation Act for fuel economy, and the Clean Air Act for emissions.

It is known in some countries as an "off-road vehicle" or "four-wheel drive", often abbreviated to "4WD" or "4x4", pronounced "four-by-four". However, not all SUVs have four-wheel drive capabilities. Conversely, not all four-wheel-drive passenger vehicles are SUVs. Off-road vehicles are a different class of vehicles, built primarily for off-road use. However, this distinction is often not made by the general public and the media. Although some SUVs have off-road capabilities, they often play only a secondary role, and SUVs often do not have the ability to switch among two-wheel and four-wheel-drive high gearing and four-wheel-drive low gearing. While auto makers tout a SUV's off-road prowess with advertising and naming, the daily use of SUVs is largely on paved roads and in urban areas. Such use causes the term SUV to be a denigrating term by owners of "real" off-road vehicles.

Extremely popular in the late 1990s and early 2000s, the SUV's popularity has since declined. Due to high oil prices and a declining economy since the mid-2000s, manufacturers have responded to buyers' complaints. The traditional truck-based SUV is gradually being supplanted by a new vehicle type, the crossover SUV, which uses an automobile platform for lighter weight and better fuel efficiency.
