Bentley Crewe, also named the Pyms Lane site after the street it is located on, is the headquarters and design and manufacturing centre of Bentley Motors Limited on the outskirts of Crewe, Cheshire, England. The site covers an area of 521,111 m² (5,609,190 sq ft), of which 166,930 m² (1,796,800 sq ft) is indoors.

In preparation for World War II, Rolls-Royce and the British government searched for a location for a shadow factory to ensure production of aero-engines. Crewe, with its excellent road and rail links, as well as being located in the northwest away from the aerial bombing starting in mainland Europe, was a logical choice. Crewe also had extensive open farming land. Construction of the factory started on a 60-acre area on the potato fields of Merrill's Farm in July 1938, with the first Rolls-Royce Merlin aero-engine rolling off the production line five months later. A total 25,000 Merlin engines were produced, employing 10,000 people at its peak in 1943.

With the war in Europe over and the general move towards the then new jet engines, Rolls-Royce concentrated its aero engine operations at Derby and moved motor car operations to Crewe.

In 1946 the factory produced its first motor car, the Ivan Evernden designed Bentley Mark VI which was based on the short lived Bentley Mark V. It was the first Bentley (or Rolls-Royce) with a standard pressed-steel body rather than different bodies designed and made by bespoke coach builders. The Bentley Mark VI was the most successful Bentley ever manufactured: Crewe produced more than 5,000 Mark VIs, which equaled the total number of Bentleys made in the 20 years before World War II.

The Derby designed Bentley R Type was produced until 1955 when it was succeeded by the Bentley S1/Rolls-Royce Silver Cloud, the first car wholly designed, developed, and built at Crewe. It was also the last Bentley fitted with a six-cylinder engine. Its successor, the Bentley S2, used the Crewe designed and developed 6.25-litre, all-aluminium, Rolls-Royce V8 engine, which remained in production in various forms until 2020.

While the Bentley R-Type and S-Type differed significantly from the corresponding Rolls-Royce models, the 1965 Bentley T-series/Rolls-Royce Silver Shadow differed only in badges and radiator grills. The Bentley models even used a Rolls-Royce badged engine. As a result, fewer Bentleys were sold, making them more valuable today. The Bentley T-series/Rolls-Royce Silver Shadow were the first models with monocoque construction and four-wheel disc brakes.

The 1980 badge engineered Bentley Mulsanne was the last Bentley to undersell its Rolls-Royce sister, in this case the Rolls-Royce Silver Spirit. When the Rolls-Royce Motor Car division was sold to Vickers plc in 1980, Bentley changed its image, resulting in the 140 miles per hour (230 km/h) Bentley Mulsanne Turbo, nicknamed the "Crewe missile", which accelerated faster than some Ferraris. After this point, while the two marques looked similar, Bentleys were designed to appeal typically to wealthy businessmen, while Rolls-Royce maintained their appeal to the traditional wealthy. The result was a surge in Bentley sales, which by 1985, had over taken Rolls-Royce sales for the first time since car production moved to Crewe.

1998 brought the launch of the all-new Bentley Arnage/Rolls-Royce Silver Seraph, the last dual-brand model, powered by a BMW 4.4 litre twin-turbo V8 engine. The same year, Vickers announced its intention to sell its car division, which included the Bentley brand and the Crewe factory but not the Rolls-Royce brand which would return to Rolls-Royce Group in the event of a sale.
