Dandridge is a town in Jefferson County, Tennessee, United States. It is the county seat of Jefferson County. It is part of the Morristown, Tennessee Metropolitan Statistical Area. Dandridge is the second oldest city in Tennessee, behind only Jonesborough. A large part of Dandridge, including most of the historic commercial center, sits below the high level water mark of Douglas Lake. The historic French Broad Baptist Church was saved from the local Tennessee Valley Authority flood control project by a member of the Swann family, who had contacted Eleanor Roosevelt for assistance.
The town is situated along the northern bank of the Douglas Lake impoundment of the French Broad River, approximately 45 miles (72 km) upstream from the river's confluence with the Holston River and Tennessee River at Knoxville, and approximately 12 miles (19 km) upstream from Douglas Dam. Dandridge is centered around the junction of Tennessee State Route 92, which connects the town to Jefferson City to the north and U.S. Route 411 across the lake to the south, and U.S. Route 70, which connects the town to Knoxville to the west and Newport to the east. Interstate 40 intersects TN-92 in the northern part of Dandridge.
