Piketon is a village in Pike County, Ohio, United States, along the Scioto River. The village is best known for the uranium enrichment plant located there (one of only three such plants in the United States). The population was 2,181 at the 2010 census. Originally called Jefferson, it was the county seat of Pike County 1815–1845, when James Emmitt, a wealthy local entrepreneur, influenced removal of the county seat to Waverly, due to its closer proximity to the then new Ohio & Erie Canal. Piketon is the location of the Pike County Fairgrounds and is served by the Scioto Valley School District.
Perhaps the best-known historic resident of Piketon was Robert Lucas, the governor of Ohio and territorial governor of Iowa. Around 1824, Lucas built a large brick house two miles east of Piketon, named Friendly Grove, which became a center of local political activity.
Piketon is served by the Western and Piketon branches of the Garnet A. Wilson Public Library.
