Loudonville is a village in Ashland and Holmes counties in the U.S. state of Ohio. The population was 2,906 at the 2000 census. Loudonville is nicknamed the "Canoe Capital of Ohio" for the many canoe liveries along the Mohican River. It is also home to Mohican State Park and Mohican-Memorial State Forest and Landoll's Mohican Castle.
Loudonville was founded on August 6, 1814, by James Louden Priest.
Loudonville was the long-time (1913–96) home of The Flxible Company, a manufacturer of motorcycle sidecars, commercial cars (hearses, ambulances, and flower cars), intercity coaches, and city-transit coaches. During World War II, Flxible interrupted its normal production and built instead a variety of war goods. A part of the former Flxible plant is now in use as a parts depot and service point for the Motor Coach Industries.
