Crazy Woman Creek is a creek in the United States, in Johnson County, Wyoming.
There are several legends about the name. It was the site of a trading post and the site of battles in the American Indian Wars. It was also a locale of the Johnson County War.
An FAA-operated VOR navigation beacon, named amusingly after this area, is located about seven miles (12 km) southeast of the creek. Crazy Woman VOR's FAA three-letter station designator is CZI.
