Loudonville is a village in Ashland and Holmes counties in the U.S. state of Ohio. The population was 2,641 at the 2010 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.
The town of Loudonville includes three places on the National Register of Historic Places. These include the Ohio Theatre (Loudonville, Ohio), which was erected in 1909 under the name of "City Hall and Opera House". The theatre had a troubled history, and was almost closed in the 1900s, but three freshman from the Loudonville High School (Ohio) raised $4,000 dollars in a local talent show. In 2009, the Ohio Theater celebrated its 100th Anniversary. The home of Phillip J. Black located at 303 N. Water Street is also listed on the National Register of Historic Places. Built in 1856 it is now home to the Blackfork Inn Bed & Breakfast.
