Fenton is a city in the U.S. state of Michigan that lies mostly in Genesee County, with small portions in neighboring Oakland County and Livingston County.
It was first established in 1834 and was originally named Dibbleville after Clark Dibble, one of the first settlers. It was platted in 1837 as Fentonville by William M. Fenton who would later become lieutenant-governor of Michigan. When the settlement was incorporated as a village in 1863 the name Fenton was used. The settlement's post office used the name Fentonville from 1837 until 1886, when it adopted the current name.
In the 1970s, the city leveled its downtown buildings and closed Leroy Street as part of an urban renewal plan. On August 24, 2007, an EF2 tornado hit Fenton, damaging several homes and a school, and almost completely destroying the soon to be opened Tractor Supply Company, tearing off its roof. This caused many people to go without power, leaving the city in a state of emergency. There were no fatalities or serious injuries. In July 2011, the first proposed building, Cornerstone, to restore the city's old downtown area was announced.
