The Butte–Anaconda Historic District is a National Historic Landmark (NHL) that spans parts of Walkerville, Butte and Anaconda, Montana, United States. It has the most resources of any U.S. National Historic Landmark District.
It was declared an NHL in 1961, when it focused only on Butte.
In 2006, the district was expanded significantly to include parts of Walkerville and Anaconda, as well as the bed of the Butte, Anaconda and Pacific Railroad. The expanded district covers 9,774 acres (39 km2) with nearly 6,000 contributing properties of historic significance.
New York's Adirondack Park and Alaska's Cape Krusenstern Archeological District are much larger by area, but may contain fewer contributing elements.
