The Rolling Mill Mine was a drift portal coal mine in operation in Johnstown, Cambria County, Pennsylvania, operating from approximately 1856 until 1931. It was originally owned by the Cambria Iron Company and was developed in the Westmont hillside across the Conemaugh River from the company's rolling mill. Its portal was near the confluence of the Stonycreek River and Little Conemaugh River. It supplied the bulk of the coal used in the iron and steel making taking place in the city, producing an average of 3,000 tons a day in 1902, and primarily employed recent immigrants from Central and Eastern Europe.
