The Ford Piquette Avenue Plant is a former factory located within the Milwaukee Junction area of Detroit, Michigan, in the United States.

At the Piquette Avenue Plant, the company created and first produced the Ford Model T, the car credited with initiating the mass use of automobiles in the United States.

[1]: 11–12  The company quickly outgrew this facility and, on April 10, 1904, bought a parcel of land off of Piquette Avenue in Detroit to accommodate a larger factory.

[1]: 4–5 From October 1904 to the end of 1909, Ford Motor Company assembled car models B, C, F, K, N, R, S, and T at the Piquette Avenue Plant.

[1]: 5, 12  Due to variations in demand and car model changeover, the number of employees varied constantly, ranging from as low as 300 to as high as 700.

[1]: 21  Ford Motor Company was a member of the Employers’ Association of Detroit, an organization that prevented most of the city's factories from unionizing until the 1930s.

[1]: 15  The success of the Model N made Ford Motor Company the largest automaker in the United States by the end of 1906, a distinction that it would hold for twenty years.

[1]: 10, 18  Much of the design and experimental work for the new car was done by Henry Ford, draftsman Joseph Galamb, engineer Childe Harold Wills, and machinist C.J.

[1]: 18  The experiments consisted of tying a rope to a Model N chassis and pulling it across the factory's third floor on skids until its axles and wheels were added.

[1]: 18  Although Henry Ford encouraged these experiments, he did not implement a formal moving assembly line at the Piquette Avenue Plant, as all of his attention was focused on getting Model T production started on time.

[1]: 18  Despite not having a moving assembly line, the Piquette Avenue Plant, aided by the usage of interchangeable parts and other production improvements, produced 101 completed cars in a single day on June 4, 1908, an auto industry record at the time.

[1]: 14  The concept of using a moving assembly line to manufacture cars would be fully implemented at the Highland Park Ford Plant, starting on October 7, 1913.

[11] Over 15 million Model T's would eventually be built, and the first 14,000 made in the United States were assembled at the Piquette Avenue Plant.

[2][7] The Ford Piquette Avenue Plant was sold in January 1911 to Studebaker, a major maker of various horse-drawn road vehicles since the 1850s.

[19] In 1936, Studebaker sold the Piquette Avenue Plant to the Minnesota Mining and Manufacturing Company (3M), a producer of rubber auto parts and non-adhesive paper tape.

[1]: 23  Since the early 1990s, a company named General Linen & Uniform Service has occupied part of the Piquette Avenue Plant's first floor.

[31] The factory's front façade was fully restored to its 1904 appearance and revealed to the public on September 27, 2008, the 100th anniversary of the completion of the first production Model T.[32] On August 11, 2011, Model T Automotive Heritage Complex membership chairman Tom Genova was honored with a ROSE Award from the Detroit Metro Convention & Visitors Bureau in the Volunteers category.

[35] On November 10, 2015, the Window Restoration Team at the Piquette Avenue Plant received a MotorCities National Heritage Area Award of Excellence in the Preservation category.

[36] Around 2016, the National Park Service considered adding the Piquette Avenue Plant to a list of places in the United States eligible for UNESCO World Heritage Site status.
