Shannon Falls is a 20-foot waterfall on Crooked Fork Creek in Morgan County, Tennessee, in the Southwestern Appalachians region. It lies about 9.4 miles northwest of Coalfield and roughly 37.6 miles west of Knoxville as the crow flies.

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. Crooked Fork Creek carries 3 recorded waterfalls, and Shannon Falls is the tallest of them.
Morgan County holds 14 recorded waterfalls, and several are close by. Lower Potters Falls, an 18-foot tiered waterfall, is under a mile away. Lamance Falls, a 20-foot punchbowl waterfall, is under a mile away. Debord Falls, a 12-foot block waterfall, is about 6.8 miles away.
