The Atlas Coal Mine National Historic Site is an inactive coal mine in Alberta, Canada that operated from 1936 to 1979. Located in East Coulee near Drumheller, it is considered to be Canada's most complete historic coal mine and is home to the country's last standing wooden coal tipple, and the largest still standing in North America. It was designated an Alberta Provincial Historic Resource in 1989 and a National Historic Site of Canada in 2002.
