The tenth generation of the Ford Thunderbird is a personal luxury car that was produced by Ford for the 1989 to 1997 model years. It was introduced on December 26, 1988 as a 1989 model alongside its sister car, the Mercury Cougar. Developed on Ford's new MN12 platform from the second quarter of 1984, the new Thunderbird featured a more aerodynamic body that was slightly shorter in overall length relative to the 1988 Thunderbird but had a nine-inch-longer wheelbase.

The Mercury Cougar is a series of automobiles that was sold by Mercury from 1967 to 2002. The model line is a diverse series of vehicles; though the Cougar nameplate is most commonly associated with two-door coupes, at various stages in its production, the model also was offered as a convertible and a hatchback. During its production as the mid-size Mercury line, the Cougar was also offered as a four-door sedan and five-door station wagon.
