Piketon is a village in Pike County, Ohio, along the Scioto River. The population was 1,907 at the 2000 census. Originally called Jefferson, it was the county seat of Pike County from 1815-1845, when it was decided by James Emmitt, a wealthy local entrepreneur, to move the county seat to Waverly due to its closer proximity to the then new Ohio & Erie Canal. It is not a large town, but a village. It is the location of the Pike County Fairgrounds, and is served by the Scioto Valley School District. Piketon is served by the Western and Piketon branches of the Garnet A. Wilson Public Library.
