The Copper Country Limited was a passenger train operated by the Chicago, Milwaukee, St. Paul and Pacific Railroad (the "Milwaukee Road") and the Duluth, South Shore and Atlantic Railway (DSS&A) between Chicago, Illinois and Calumet, Michigan, in Michigan's Upper Peninsula.

[1] According to historian Jim Scribbins the name "Copper Country Limited" was first used in March 1907 to describe an existing Chicago–Champion, Michigan–Calumet service which had run since 1899.

As ridership continued to slide the Milwaukee offered the sleeper only three days a week beginning in the spring of 1964.

Its existence persisted almost entirely because of the lucrative U.S. mail contracts that kept many similar trains running across the country.

The southbound Copper Country Limited left Calumet at 5 p.m., stopped at Champion from 7:40 to 7:50 p.m., Green Bay from 1:15 to 1:45 a.m., Milwaukee from 5:15 to 6:05 a.m. and arrived at Chicago at 7:45 a.m.
