Kingsbridge branch line was a single track branch line railway in Devon, England. The railway, which became known as the Primrose Line, opened in 1893 and, despite local opposition, closed in 1963. It left the Exeter to Plymouth line at Brent and ran 12 miles (19 km), following the route of the River Avon, to Kingsbridge. A proposed extension to Salcombe was not constructed.
