Peru is a town in Clinton County in the U.S. state of New York. The population was 6,998 at the 2010 census. The town was named Peru because the mountainous nature of its western reaches suggested that country. Peru is in the southeastern part of Clinton County, south of Plattsburgh.
Peru was formed from parts of the towns of Plattsburgh and Willsboro (the latter now in Essex County) in 1792. Part of Peru was returned to Willsboro in 1799. In 1838, part of the town was used to form the towns of Au Sable and Black Brook.
On April 20, 2002, around 6:50 am, a magnitude 5.2 earthquake was centered in the western part of Peru, southwest of Plattsburgh. The earthquake was felt as far north as Montreal, as far west as Cleveland, Ohio, as far south as Baltimore, Maryland, and throughout New England to the east. No injuries or deaths were reported, but moderate damage in the surrounding area was common, including partial road collapses, fallen chimneys, and broken windows.
