West Virginia Route 115 is a state highway running south to north in Jefferson County in West Virginia's Eastern Panhandle. The southern terminus of the route is at WV 9 near Mannings. The northern terminus is also at WV 9 north of Ranson.

WV 115 is the old alignment of WV 9 through Ranson and Charles Town. It ceased being part of WV 9 when the WV 9/US 340 bypass was built.

Route 115 was assigned to the old section of WV Route 9 that winds up Blue Ridge Mountain to the Virginia state line. The designation of Route 115 occurred in November 2012 when the new 4-lane Route 9 from Charles Town to the Virginia state line was opened to traffic.
