Mercury is an automobile marque of the Ford Motor Company founded in 1939 to market entry-level-luxury cars slotted between Ford-branded regular models and Lincoln-branded luxury vehicles, similar to General Motors' Buick (and former Oldsmobile) brand and Chrysler's Chrysler brand. Today, all Mercury models are based on Ford platforms. The Mercury name comes from the "messenger of the gods" of Roman mythology, and during its early years, the Mercury brand was known for performance, which was briefly revived in 2003 with the Mercury Marauder.

The Mercury brand is used in the United States, Mexico, Puerto Rico, U.S. Virgin Islands, and the Middle East. In 1999 the Mercury brand was dropped in Canada, although the Grand Marquis is still marketed there and wears a Mercury badge.
