The Solihull plant is a car manufacturing factory on Lode Lane in Solihull, England, around 7 miles (11 km) to the southeast of Birmingham city centre. It is the largest Jaguar Land Rover factory. The plant sits on a 300-acre (120 ha) site and employs over 10,000 people in manufacturing. Some Land Rover vehicles are produced here, including the Range Rover Sport.

The plant was originally built by the UK Government in the 1930s and was used to manufacture aircraft engines during and shortly before World War II. It has previously been owned by the Rover Company and British Leyland; it is now owned by Tata Motors Passenger Vehicles.

Originally two farms, Wharhall and Fordrove, were purchased in 1936 by the British Government on which to build a shadow factory in preparation for any potential war with Nazi Germany. Construction was started almost immediately, with the factory complete as a shell and placed in mothballs in late 1938.

At the outbreak of World War II in September 1939, the factory was allocated to the Coventry-based Rover Company, who were assigned the task to build Bristol Hercules engines. Named No.2 Solihull, after starting fitting out initial production was undertaken in Acocks Green, with machined parts supplied from Drakelow. Rover took possession of the fitted-out factory in January 1940, and produced the first Rover-built Hercules engine in October 1940. The factory became a guarded and fortified location, and air raid shelters are still in the grounds of the plant. The oldest part of the Rover factory is the present day South Works, with its late 1930s art deco facade still with wartime camouflage.

The engines were to be used in either planes or tanks, specifically Bristol Beaufighters and Handley Page Halifaxes, but mainly Short Stirlings. Locally, the majority of engines were shipped to the Austin Motors Elmdon factory at Cofton Hackett, part of the Longbridge plant, which produced the Stirling.

In 2010 as part of the Land Rover Legacy Project, the Heritage Motor Centre sponsored a project to research and note the history of the factory.

Rover's main Coventry car factory had been extensively damaged during the Nazi bombing of Coventry. Rover had negotiated an option to use the Solihull plant if their own was not viable to use at the war's end and in 1945 the Rover Company officially relocated from Coventry to the Lode Lane plant. As in the tradition of Rover previous main factories dating back to the original Starley and Sutton Rover Bicycle plant from Victorian times, the Solihull plant was named The Meteor Works. Car production started again in 1946, with the first new car to be produced at the factory the Rover P4, from 1949. As well as producing many Rover cars there until the late 1970s, the plant was also the development site of the Land Rover four-wheel drive vehicle in late 1947 and 1948. It is also the development site for Rover's other four wheel drive in the late 1960s, the Range Rover. The Land Rover instantly began out selling Rover cars from its beginning in 1948 and the Solihull plant has remained the home and birthplace of Land Rover ever since, being the principal assembly plant for both the classic Land Rover (both Series and Defender) and the full-size Range Rover for their entire production runs.

North Works was added to the Solihull site beginning in late 1956 as two storage warehouses. North Works became a complete factory of its own for the introduction of the Rover P6 car in October 1963. The Rover P6 was awarded the International Car of the Year for 1964.
