旅行车（英语：station wagon）是结合中型轿车和掀背车特点的一种车型，是将三厢轿车的车身将其车顶向后延伸与尾部结合，并将行李厢门改成掀背式尾门，同时拥有轿车的长度与掀背车的设计。第三个或第五个门可是掀背式或挡板，车身造型可转换成一个标准的三箱设计两箱的设计包括一个A，B，C柱，以及一个D-支柱。旅行车并可以灵活地重新折叠式后排座椅。美国传统词典定义为“一个或多个行可折叠或可移动的座位和无行李舱的汽车，但背后的挡板可放置行李箱，包裹等。在1969年，大众机械师说：“旅行车它是一个对口的，大部分是相同的轴距，提供了相同的变速器和发动机，同样的舒适和便利的选择。”

A station wagon, also called an estate car, estate wagon, or simply wagon or estate, is an automotive body-style variant of a sedan/saloon with its roof extended rearward over a shared passenger/cargo volume with access at the back via a third or fifth door (the liftgate or tailgate), instead of a trunk lid. The body style transforms a standard three-box design into a two-box design — to include an A, B, and C-pillar, as well as a D-pillar. Station wagons can flexibly reconfigure their interior volume via fold-down rear seats to prioritize either passenger or cargo volume.
