East Fork Obey Falls is a 20-foot waterfall on East Fork in Fentress County, Tennessee, in the Southwestern Appalachians region. It lies about 3.1 miles west of Grimsley and roughly 65.7 miles west of Knoxville as the crow flies.
At 20 feet it is on the modest side for Tennessee, where the typical waterfall with a recorded height stands around 30 feet; it ranks 199th of 332. By form it is a block waterfall, wider than it is tall, spilling over a broad ledge.
The Southwestern Appalachians are the Cumberland Plateau and its escarpments, a sandstone tableland covered in oak and mixed mesophytic forest and cut by deep gorges. Creeks pour off the plateau rim over sandstone caprock into gorges, creating many tall, dramatic falls.
