This is an incomplete List of ghost towns in Montana. A ghost town is a town or city which has lost all of its businesses and population. A town often becomes a ghost town because the economic activity that supported it has failed, or due to natural or human-caused disasters such as a flood, government action, uncontrolled lawlessness, or war. The term is sometimes used in a deprecated sense on the internet to include cities, towns, and neighborhoods which, while still populated, are significantly less so than in years past.
