The Plymouth Valiant (first appearing in 1959 as simply the Valiant) is an automobile which was marketed by the Plymouth division of the Chrysler Corporation in the United States from the model years of 1960 through 1976. It was created to give the company an entry in the compact car market emerging in the late 1950s. The Valiant was also built and marketed, without the Plymouth brand, worldwide in countries including Argentina, Australia, Brazil, Canada, Finland, Mexico, New Zealand, South Africa, Sweden and Switzerland, as well as other countries in South America and Western Europe. It became well known for its excellent durability and reliability, and was one of Chrysler's best-selling automobiles during the 1960s and 1970s, helping to keep the company solvent during an economic downturn.
Road & Track magazine considered the Valiant to be "one of the best all-around domestic cars".
In May 1957, Chrysler president Lester Lum "Tex" Colbert established a committee to develop a competitor in the burgeoning compact car market which included the popular VW Beetle, the new American Motors Rambler and upcoming entries from GM, Ford and Studebaker. Design chief Virgil Exner created a car that was smaller and lighter than a full-size car without sacrificing passenger and luggage space. Originally named the "Falcon" after Exner's 1955 Chrysler Falcon concept car, the vehicle was renamed the "Valiant" (which means "having or showing courage or valor") honoring Henry Ford II's request to use the name for the Ford Falcon. The Valiant debuted at the 44th British International Motor Show in London on October 26, 1959. It was introduced as a 1960 model and was officially considered a distinct brand, advertised with the tagline "Nobody's kid brother, this one stands on its own four tires." For the 1961 model year, the Valiant was classified as a Plymouth model. The 1961–62 Dodge Lancer was essentially a rebadged Valiant with different trim and styling details.
