Start Point is a promontory in the South Hams district in Devon, England, grid reference SX832370. Close to the most southerly point in the county, it marks the southern limit of Start Bay, which extends northwards to the estuary of the River Dart. The rocks of the point are greenschist and mica-schist, formed by metamorphism of Devonian sediments during a period of mountain building towards the end of the Carboniferous period.
