Tiffin River Wildlife Area is a four hundred sixty-five-acre state wildlife management area in western Fulton County, Ohio, along Ohio State Route 66 between Fayette and Archbold. Its protected land is non-contiguous, divided into separate parcels rather than a single continuous tract. The area is managed for wildlife use and is open to hunting. The Ohio Department of Natural Resources has released pheasants here for hunters, and access is available from a parking lot off County Road 23.
