Amberley Museum is an open-air industrial heritage museum at Amberley, near Arundel in West Sussex, England. The museum is owned and operated by Amberley Museum and Heritage Centre, a not-for-profit company and registered charity, and has the support of an active Friends organisation. The items in the Museums collection are held by The Amberley Museum Trust

The museum was founded in 1978 by the Southern Industrial History Centre Trust and has previously been known as the Amberley Working Museum, Amberley Chalk Pits Museum, and Amberley Museum and Heritage Centre. It is located within historic chalk quarries. Chalk was extracted and processed for lime on site for more than 100 years, and the museum still houses a number of its original lime kilns. In addition, holdings and exhibitions at the museum cover a diversity of industrial and local heritage collections, including narrow gauge railways, local bus services, and a multitude of light and rural industrial subjects.

The open-air museum is 36-acre (146,000 m), located next to Amberley railway station and dedicated to the industrial heritage of South East England and with a special interest in aspects of the history of communications and transport.

The museum is sited in a former chalk quarry where the chalk was converted into lime for use in mortar and cement, and remaining on site are several kilns, including a De Witt set, and associated buildings including offices, bagging shed and locomotive shed.

Also to be seen is the quarry tunnel, which appeared as Mainstrike Mine in the James Bond film A View to a Kill. Additional buildings have been relocated or replicated on the site and exhibition halls added. The natural history and geology of the site can be seen from a nature trail.

The site hosts a range and exhibitions and collections most of which can be seen though they may not be operational when the museum is open.
