The Chicago, Milwaukee, St. Paul and Pacific Railroad (ACMStP&P), better known as the Milwaukee Road (reporting mark MILW), was a Class I railroad that operated in the Midwest and Northwest of the United States from 1847 until 1986.

The company experienced financial difficulty through the 1970s and 1980s, including bankruptcy in 1977 (though it filed for bankruptcy twice in 1925 and 1935, respectively). In 1980, it abandoned its Pacific Extension, which included track in the states of Montana, Idaho, and Washington. The remaining system was merged into the Soo Line Railroad (reporting mark SOO), a subsidiary of Canadian Pacific Kansas City (reporting mark CPKC), on January 1, 1986. Much of its historical trackage remains in use by other railroads. The company brand is commemorated by buildings like the historic Milwaukee Road Depot in Minneapolis and preserved locomotives such as Milwaukee Road 261 which operates excursion trains.
