The DeSoto Adventurer was a passenger car manufactured by Chrysler under the DeSoto brand from 1956 to 1960. During this time, the Adventurer was the brand's top model. In 1956 it was only offered as a hardtop coupé. In 1957 a convertible was added. In the last year of production there was no longer a convertible, but a 4-door hardtop sedan. Chrysler announced the closure of DeSoto in November 1960; the production was kept up until the prefabricated DeSoto logos were installed.
