Yes, indirectly. The Tennessee River flows into the Ohio River, which then flows into the Mississippi.
The three canals that connect the Great Lakes to the Ohio River are the Erie Canal, the Chicago Sanitary and Ship Canal, and the Ohio and Erie Canal. The Erie Canal links Lake Erie to the Hudson River, which eventually connects to the Atlantic Ocean. The Chicago Sanitary and Ship Canal provides a route from Lake Michigan to the Illinois River, leading to the Mississippi River system. The Ohio and Erie Canal directly connects Cleveland on Lake Erie to the Ohio River, facilitating trade and navigation.
