Mount Vernon is the county seat and largest city in Posey County, named for General Thomas Posey, Governor of the Indiana Territory. He grew up at a plantation adjacent to George Washington's Mount Vernon. He was widely rumored to be Washington's illegitimate son, but this was dismissed by Posey's biographer, John Thornton Posey, a descendant.[10]

The first settler in Mount Vernon was Andrew McFaden in 1806, and the settlement was called McFaden's Bluff. It was platted as Mount Vernon in 1816, but continued to be known as McFadden's Bluff for some time.[11] It was named in honor of Washington's Mount Vernon. A post office called Mount Vernon has been in operation since 1818.[12]

A number of historic sites have been recognized in Mount Vernon, including the Posey County Courthouse Square, Mount Vernon Downtown Historic District, Welborn Historic District and the William Gonnerman House, all of which have been placed on the National Register of Historic Places.[13]
