Orcheston (OR-Chest-ton) is a civil parish and village in Wiltshire, England, lying on Salisbury Plain less than a mile north-west of neighbouring Shrewton.

The manor is recorded in the 1086 Domesday Book with the spelling Orcestone in three entries and Orchestone in a fourth.

[10] As of 2009, Orcheston contains about sixty-five houses, of which twenty-six are listed buildings, and has a single parish council.

[18] Maurice Roy Ridley (1890–1969), writer and poet, Fellow and Chaplain of Balliol College, Oxford, was born in Orcheston.

Dorothy L. Sayers is reputed to have based the appearance of her fictional detective Lord Peter Wimsey on him.
