The Mercury Turnpike Cruiser was a halo model of the Mercury Division of the Ford Motor Company that was produced from 1957 to 1958.

The Turnpike Cruiser, built as a two and four door hardtop only, is best known for its unique styling cues and wide array of gadgets including a power rear window that could be lowered to improve ventilation, and "twin jet" air intakes at upper corners of car's windshield.

For 1957, the Turnpike Cruiser was the premium model range for Mercury. In addition to its unique features, the car was further differentiated from other Mercury models by a gold anodized trim strip in the cars rear fin. In 1958 the Turnpike Cruiser joined the mid-range Mercury Montclair line with only minor trim changes to the car from the previous year.

The Turnpike Cruiser was discontinued for 1959. However from 1963 to 1966 Mercury revived the Turnpike Cruisers most noted feature, the retractable rear window, on its "Breezeway" sub-series in the Monterey, Montclair and Park Lane model ranges.
