The Ford River Rouge Complex (commonly known as the Rouge Complex or just The Rouge) is a Ford Motor Company automobile factory complex located in Dearborn, Michigan, along the Rouge River, upstream from its confluence with the Detroit River at Zug Island. Construction began in 1917, and when it was completed in 1928 it had become the largest integrated factory in the world.

The Rouge measures 1.5 miles (2.4 km) wide by 1 mile (1.6 km) long, including 93 buildings with nearly 16 million square feet (1.5 km²) of factory floor space. With its own docks in the dredged Rouge River, 100 miles (160 km) of interior railroad track, its own electricity plant, and integrated steel mill, the titanic Rouge was able to turn raw materials into running vehicles within this single complex, a prime example of verticalintegration production. Over 100,000 workers were employed there in the 1930s.
