Mercury is a defunct division of the American automobile manufacturer Ford Motor Company. Created in 1938 by Edsel Ford, Mercury served as the medium-price brand of Ford for nearly its entire existence, bridging the price gap between the Ford and Lincoln model lines. Competing against Buick and Oldsmobile from General Motors for decades, the brand also competed against Chrysler's namesake brand (following the closure of DeSoto).

From 1945 until its closure, Mercury formed half of the Lincoln-Mercury Division of Ford, which served as a combined sales network (distinct from Ford) for its two premium automotive brands. Lincoln-Mercury also served as the sales network for Continental (1956–1960), Edsel (1958–1960) and Merkur (1985–1989). Through the use of platform sharing and manufacturing commonality, Mercury vehicles shared components and engineering with Ford or Lincoln (or both concurrently), serving as counterparts for vehicles from both divisions.

Following an extended decline in sales and market share for Mercury, Ford announced the closure of the division at the end of 2010.
