The East Webburn is a stream in the Dartmoor moors in Devon in south-west England. It rises on the western side of the moors flowing off the west side of Hameldown ridge. Its source is less than 1 kilometre south west of Grimspound Bronze Age settlement. It flows south past Widecombe-in-the-Moor and joins the West Webburn River at Lizwell Meet in Oakmoor Wood. These combined streams then join the River Dart close to the village of Holne.
