The Haldon Hills, usually known simply as Haldon, is a ridge of high ground in Devon, England. It is situated between the River Exe and the River Teign and runs northwards from Teignmouth, on the coast, for about 24 km (15 mi) until it dwindles away north west of Exeter at the River Yeo, just south of Crediton. The highest points of just over 250 metres (820 ft) lie to the south west of Exeter.
