The Ford Crown Victoria is a rear-wheel drive full-size car first produced by the Ford Motor Company for the North American market in the mid-1950s. Its current incarnation has been in production since 1992 at Ford's St. Thomas Assembly plant.

The Crown Victoria, and its Mercury and Lincoln stablemates, are the only full-frame rear-wheel-drive passenger cars built in North America. As of 2008 it is only available for fleet sales.

The Crown Victoria was replaced as Ford's flagship with the introduction of the 2005 Ford Five Hundred. However, the 5,424 Crown Victorias sold in January 2007 far exceeded the 3,526 of the newer Five Hundred (rebranded as the Taurus in 2008) which was a more technically advanced full-size car with similar passenger space and better fuel economy. But while newer front-wheel drive platforms may have been popular among consumers, they have not challenged the Crown Victoria's dominance as a taxi cab, fleet vehicle and police car where durability, cost and performance rather than efficiency are top requirements. The "Crown Vic" remains popular for these applications due to its conventional rear-wheel drive, V8 power, popular with police driving techniques. As one of the few remaining passenger cars with body-on-frame construction, it is rugged, and enables repairs after minor accidents without the need to straighten the chassis – an important benefit for a car frequently used by police forces for PIT maneuvers: ramming a car to spin it out. The Crown Victoria is one of the few surviving US vehicles still in production with features such as the column-mounted gear shift and a two-bench, six-passenger seating layout, which has otherwise largely been replaced by the two front-bucket layout popularized by imports.

Retail sales dwindled to just 3,000 in 2006, compared to 38,280 of its stablemate Mercury Grand Marquis in the first nine months of 2007. Following its withdrawal from Canadian retail dealers, the Crown Victoria has been limited in the US market since the 2008 model year to fleet sales, which constituted 95% of its total sales in recent years. The Mercury Grand Marquis, as well as the platform-sharing Lincoln Town Car, will continue to be available to retail consumers. A longer wheelbase version is available for taxi use.

While the Crown Victoria shares its platform and components with the Lincoln Town Car, it shares almost no exterior sheet metal or interior parts. The current model has had a number of upgrades. Since the exit of General Motors from rear-drive full-size cars with the Chevrolet Caprice, it held a near-monopoly as a pursuit vehicle in North America, despite front-wheel-drive offerings such as the Chevrolet Impala. However, the Dodge Charger has started to challenge this dominance with some significant adoptions among police and taxi fleets since its introduction. While there has been speculation of replacements, some based on the slightly smaller Australian Falcon, no firm plans have been announced by Ford; however the similar Grand Marquis has since been replaced by the Ford Taurus as the sole full-size offering in Canada.
