A station wagon, also known as an estate car, is an automotive body-style variant of a sedan/saloon with its roof extended rearward over a shared passenger/cargo volume with access. The American Heritage Dictionary defines a station wagon as "an automobile with one or more rows of folding or removable seats behind the driver and no luggage compartment but an area behind the seats into which suitcases, parcels, etc., can be loaded through a tailgate". Station wagons have evolved from their early use as specialized vehicles to carry people and luggage to and from a train station, especially to estates, and have been marketed worldwide. The first all-steel station wagon was the 1935 Chevrolet Suburban, which was built on the chassis of a panel truck. However, most station wagons were produced with wooden bodies until after World War II. The first postwar station wagon to be based on a passenger car chassis was the 1949 Plymouth Suburban, which used a two-door body style. Several manufacturers produced steel and wooden-bodied station wagons concurrently for several years.

The name "station wagon" comes from the early use of these vehicles to carry people and luggage to and from train stations. The supply of the station wagon body style has faded since the 2010s in favor of the crossover SUV. However, some automakers still produce station wagons, which offer greater utility and flexibility than a similarly sized sedan. Modern station wagons include the Subaru Forester, Mercedes-AMG E63, and several Audi automobiles.
