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.





Current Status:

In 1990, the last seven residents made national headlines when they reluctantly voted to disincorporate, ending their town’s status as an officially recognized city. At the disincorporation hearing Matt Porter, who had served as the town’s mayor for 35 years, stated “Three of us are in our 70s and sooner or later it’s got to come. There’s no one else to carry on”. Donnan ceased to exist in March 1991; the final vote was 6 to 1 in favor of disincorporation.


A monument on New Donnan Road pays tribute to the empty community, which lies just two miles (3 km) north of its nearly empty sister community of Randalia (population 68). In October 2007, like Donnan before it, Randalia lost its post office, some time after losing its school and general store. Matthew Porter died in a fire in his home in Donnan in 2009.
