The John Ownby Cabin is a historic cabin in Sevier County, Tennessee, United States. Located in The Sugarlands, it lies within the boundaries of the Great Smoky Mountains National Park. It was built in 1860, and is the last surviving structure from the pre-park Forks-of-the-River community. Repairs were carried out on the dilapidated cabin in 1964, which included replacing the front porch, and the cabin was added to the National Register of Historic Places in 1976. The cabin currently stands along the Sugarlands Nature Trail, an interpretive trail accessible behind the Sugarlands Visitor Center.
