密尔沃基铁路（Milwaukee Road，官方名称为Chicago, Milwaukee, St. Paul and Pacific Railroad）是自1847年开始在美国中西部、西北部运营的一条一级铁路，1986年1月1日并入苏线铁路公司。虽然不再作为独立的铁路存在，但历史建筑密尔沃基火车站中依然有对该铁路的纪念说明、密尔沃基铁路261号蒸汽机车仍得以保存。

The Chicago, Milwaukee, St. Paul and Pacific Railroad (often referred to as the Milwaukee Road) (reporting markMILW), was a Class I railroad that operated in the Midwest and Northwest of the United States from 1847 until 1980, when its Pacific Extension (Montana, Idaho, and Washington) was abandoned following a bankruptcy. The eastern half of the system merged into the Soo Line Railroad on January 1, 1986. The company went through several official names and faced bankruptcy several times in that period. The railroad no longer exists as a separate entity, but much of its trackage continues to be used by its successor and other roads, and is commemorated in buildings like the historic Milwaukee Road Depot in Minneapolis, Minnesota and in railroad hardware still maintained by railfans, such as the Milwaukee Road 261 steam locomotive.
