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.

The DB5 is best-known for its role in the James Bond films. It was first driven by the fictional spy in the film Goldfinger (1964). In 2013, the car featured on a "British Auto Legends" postage stamp issued by the Royal Mail.
