Membury services is a motorway service station on the M4 motorway, located on the original site of RAF Membury in the civil parish of Lambourn in the English county of Berkshire, close to the boundary with Wiltshire, 4 miles (6.4 km) west of Junction 14.

[2] It was designed by Howard V Lobb, to have three restaurants:[3] The eastbound side only opened for petrol and toilets in February 1972, but there were no meals until October 1972.

The service area is on the Theale to Shefford Woodlands section, which is 16.5 miles (26.6 km); the route was announced in December 1966, but altered in November 1967 after objections.

[7] Membury is one of five services which have a Starbucks drive-thru: the others are Fleet (Northbound only) M3, Warwick (Southbound only) M40, Hartshead Moor (Eastbound only) M62 and Gordano M5.

The service station is one of fourteen for which large murals were commissioned from artist David Fisher in the 1990s, designed to reflect the local area and history.
