The Buick Sport Wagon was a mid-size station wagon built by Buick and was shared with the Oldsmobile Vista Cruiser, Pontiac Tempest Safari and Chevrolet Chevelle Greenbrier. Featuring a raised roof and skylights over the cargo and second seat area, this model was an extended wheelbase version of the Buick Skylark station wagon. Buick Sport Wagons were built in three generations, spanning 1964–67, 1968–69, and 1970–72. During this time period, this was the only luxury level station wagon offered under the Buick model line until 1970 when the Buick Estate Wagon was returned as a full-size station wagon.

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.
