The Dorset Cursus is a Neolithiccursus monument that spans across 10 km (6¼ miles) of the chalk downland of Cranborne Chase in east Dorset, United Kingdom. Its extreme length makes it a notable example of this class of linear earthwork; it is better interpreted as a pair of same-length cursus constructed end to end, with the more southerly cursus (the Gussage Cursus) pre-dating the northerly one (the Pentridge Cursus).
