The Aston Martin DB5 is a British grand tourer (GT) produced by Aston Martin and designed by Italian coachbuilder Carrozzeria Touring Superleggera. Originally produced from 1963 to 1965, the DB5 was an evolution of the final series of DB4. The "DB" designation is from the initials of David Brown who built up the company from 1947 onwards.

A grand tourer (GT) is a type of car that is designed for high speed and long-distance driving due to a combination of performance and luxury attributes. The most common format is a front-engine, rear-wheel-drive two-door coupé with either a two-seat or a 2+2 arrangement. Grand tourers are most often the coupé derivative of luxury saloons or sedans. Many iconic car models, such as the Ferrari 250 GT, Jaguar E-Type, and Aston Martin DB5, are considered classic examples of gran turismo cars.
