South Hams is a local government district on the south coast of Devon, England. It contains the towns of Dartmouth, Kingsbridge, Ivybridge, Salcombe, and Totnes.

To the north it includes part of Dartmoor National Park, to the east borders Torquay, and to the west Plymouth. It contains some of the most unspoilt coastline on the south coast, including the promontories of Start Point, and Bolt Head.

The South Hams is the last British refuge of the Cirl Bunting.

In the Anglo-Saxon era the South Hams was a feudal estate consisting of all of the land between the River Plym and River Dart and south of Dartmoor with the English Channel forming the southern boundary. In 1967 the suburban towns of Plympton and Plymstock were detached from the South Hams and amalgamated with the City of Plymouth.
