The Cornwallis Valley Railway (CVR) was a historic Canadian railway in Nova Scotia's Annapolis Valley. It was built in 1889 and ran 13.6 miles (21.9 km) from Kentville to Kingsport serving the Cornwallis Township area of Kings County. For most of its history, it operated as a branch line of the Dominion Atlantic Railway and was sometimes known as the "Kingsport Line".
