The Studebaker Wagonaire was a station wagon produced by the Studebaker Corporation of South Bend, Indiana, from 1963–1966. It featured a retractable sliding rear roof section that allowed the vehicle to carry items that would otherwise be too tall for a conventional station wagon of the era.

A station wagon or estate car, is an automotive body-style variant of a sedan with its roof extended rearward over a shared passenger/cargo volume with access at the back via a third or fifth door, instead of a trunk/boot 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.
