The A379 is a road in the English county of Devon. It links points on the edges of that county's two principal cities, Exeter and Plymouth, by an indirect and largely coastal route. The A38 provides a faster and more direct inland route between Exeter and Plymouth, whilst the A380 provides a similarly faster route between Exeter and the Torbay area. However the A379 serves many small coastal communities and ports along the coast. The indented nature of the South Devon coast means that the road is usually out of sight of the sea, but the many rivers and estuaries are crossed by bridges and, in one case, a cable ferry.

Torbay is a unitary authority with a borough status in the ceremonial county of Devon, England. It is governed by Torbay Council, based in the town of Torquay, and also includes the towns of Paignton and Brixham. The borough consists of 24.27 sq mi (62.9 km2) of land around the east-facing Tor Bay, part of Lyme Bay on the English Channel. A popular tourist destination, Torbay's sandy beaches, mild climate and recreational and leisure attractions have given rise to its nickname of the English Riviera. The neighbouring districts are South Hams and Teignbridge.
