Bolventor (Cornish: Bedhasbold) is a hamlet on Bodmin Moor in Cornwall, England, United Kingdom. It is situated in Altarnun civil parish between Launceston and Bodmin.
The hamlet has been said to take its name from the "Bold Venture" that it must have appeared to build a farm in this moorland, but this is probably folk etymology, as "Bol-" is a common prefix in Cornish placenames. It is much more likely that the name derives from the 'Bold Adventure' tin-working area which was in operation near Jamaica Inn during the 1840s-1850s
Bolventor is the location of the famous Jamaica Inn coaching inn. It is bypassed by a dual carriageway section of the A30 trunk road; before the bypass was built the hamlet straddled the A30 road.
Daphne du Maurier, a former resident, chose Bolventor as the setting for her novel about Cornish smugglers titled Jamaica Inn. The inn that inspired the novel, Jamaica Inn, has stood beside the main road through the village since 1547. It is now a tourist attraction in its own right and dominates the hamlet.
