The name Mayfair[4] was applied to the 1951–1953 Packard 250 as a hardtop coupe nameplate built by the Packard Motor Corporation in an attempt to compete in this body style with the Oldsmobile 98 Holiday, Buick Roadmaster Riviera, Lincoln Capri and Chrysler New Yorker Newport hardtop coupes.

It was named for the City of Westminster's luxurious district Mayfair in London, England.

[1] The coupe body style was also used for a convertible, while the Mayfair model name was exclusive to the hardtop.

[1] When the Packard body style was updated for 1951, the door handle was concealed and aligned with the chrome beltline that surrounded the side windows, bottom of the windshield and rear window.
