The Austin Cambridge (sold as A40, A50, A55, and A60) is a motor car range produced by the Austin Motor Company, in several generations, from September 1954 through to 1969 as cars and to 1971 as light commercials. It replaced the A40 Somerset and was entirely new, with modern unibody construction. The range had two basic body styles with the A40, A50, and early A55 using a traditional rounded shape and later A55 Mark IIs and A60s using Pininfarina styling.

The A40 number was re-used on a smaller car (the Austin A40 Farina) from 1958 to 1967, and that the Cambridge name had previously been used to designate one of the available body styles on the pre-war 10 hp range.

The Austin Cambridge was initially offered only with a 4-passenger, 4-door saloon body, although a few pre-production 2-door models were also made. It had a modern body design with integrated wings and a full-width grille. Independent suspension was provided at the front by coil springs and wishbones but a live axle with anti-roll bar was retained at the rear.

A van derivative introduced in November 1956 and a coupé utility (pick up) introduced in May 1957 and remained available until 1974, some 3 years after the demise of the cars on which they had been based.

A 1.2-litre straight-4 pushrod engine B-Series engine based on the one used in the previous Austin Somerset (although sharing no parts) powered the new Austin Cambridge. A maximum power output of 42 bhp (31 kW) was claimed: power was transmitted to the wheels by means of a four-speed gear box controlled with a column-mounted lever.

The A40 Cambridge was intended to be available in both two-door saloon and four-door saloon variants; however, the two-door body style did not reach production.

Only 30,666 A40 Cambridge models were produced. After the A40 Cambridge was dropped early in 1957, the A40 name was re-used on the smaller A40 Farina, though that car, the 'Countryman' version of which was an early example of a hatchback, was neither a replacement nor much related to the A40 Cambridge.
