The Anaconda Copper Mine was a large copper mine in Butte. It was bought in 1881 by Marcus Daly, who developed it in partnership with George Hearst, father of William Randolph Hearst, and James B. Haggin and Lloyd Tevis of San Francisco. From this beginning grew the Anaconda Copper Mining Company, a global mining enterprise featuring the Anaconda and other Butte mines, a smelter at Anaconda, Montana, processing plants in Great Falls, Montana, the American Brass Company, and many other properties, mostly in the United States and Chile.

The Anaconda mine itself was closed in 1947 after producing 94,900 tons of copper. Its location has been consumed by the Berkeley Pit, a vast open-pit mine.

The Anaconda copper mine appeared in Don Rosa's The Life and Times of Scrooge McDuck (Part 4). Where Scrooge became owner of the whole mine as a result of a little known law stating that the whole of an ore body belongs to the one who owns the land where the body is closest to the surface. Don Rosa had, by his own statement, based this story on an actual incident in the history of the Anaconda mine.
