Dittisham is a village and civil parish in the South Hams district of the English county of Devon. It is situated on the west bank of the tidal River Dart, some 2 miles upstream of Dartmouth. The Greenway Ferry carries pedestrians across the river from Dittisham to Greenway Quay, adjacent to the Greenway Estate. Once the home of the crime writer Agatha Christie, this has views across the river, and the house and gardens are now owned by the National Trust and are open to the public.
