Mercury was an automobile marque of the Ford Motor Company launched in 1938 by Edsel Ford, son of Henry Ford, 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 namesake brand. From 1945 to 2011, it was the Mercury half of the Lincoln - Mercury division of Ford (the Edsel brand was included in that division for the 1958-1960 model years). Using badge engineering, the majority of Mercury models were based on Ford platforms.

The name "Mercury" is derived 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 brand was sold 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 was still marketed there wearing a Mercury badge through 2007.
