Donnan is a former city in the U.S. state of Iowa, located in central Fayette County. For many years, this farm hamlet was Iowa's smallest incorporated city. The town's population slowly eroded over the years; by 1990 the population had dropped to 7, and the remaining residents voted to disincorporate. Donnan ceased to exist as a city in early 1991.
