Aston Martin Lagonda Ltd. is a British luxury car manufacturer, based in Newport Pagnell in Buckinghamshire. Up to the year 2003, a total of approximately 20,200 cars had been built by Aston Martin. Today, the company is part of the Premier Automotive Group division of Ford Motor Company.

Aston Martin was founded in 1914 by Lionel Martin and Robert Bamford. In 1922, it produced cars to compete in the French Grand Prix, and set world speed and endurance records. In 1936, the company, now owned by Sir Arthur Sutherland, decided to concentrate on road cars.

In 1947, David Brown Limited bought the company under the leadership of managing director Sir David Brown—its "post-war saviour". David Brown also acquired Lagonda in that year, and both companies shared resources and workshops. In 1954, David Brown bought the site at Tickford Street in Newport Pagnell, and that was the beginning of the classic series of cars bearing the initials 'DB'.

In December 2003, Aston Martin announced they would return to motor racing in 2005. A new division was created, called Aston Martin Racing, who will be responsible, together with Prodrive, for the design, development, and management of the DBR9 program. The DBR9 will compete in the GT class in sports car races including the world-famous 24 hours of Le Mans.
