Crystal Falls is a city and the county seat of Iron County, Michigan. The city is located within Crystal Falls Township, but is a separate municipal entity. The area first developed as a major center for iron mining and the timber industry; it has become increasingly popular for tourism in recent years.

Crystal Falls was platted in 1881. It was named for a nearby icy waterfall on the Paint River. A post office called Crystal Falls has been in operation since 1885.

According to the United States Census Bureau, the city has a total area of 3.61 square miles (9.35 km²), of which 3.47 square miles (8.99 km²) is land and 0.14 square miles (0.36 km²) is water. The city is very hilly and the castle-like county courthouse (built in 1890) sits on the highest point, overlooking the downtown business district.
