Miles Barne (October 1718 – 27 December 1780) was an English land-owner and a Member of Parliament for Dunwich between 1747 and 1754, and again between 1764 and 1777. Born into a family long associated with London merchant circles, Barne accumulated sufficient wealth to purchase an estate in Suffolk and became prominent amongst local freeman. Dunwich in Suffolk, his constituency, was a pocket borough, controlled by the Downing land-owning family; Barne, the local Vanneck family and the freemen of the borough slowly ousted the Downings' influence and Barne established himself as one of the town's new members, which gave his family the seat until it was abolished in the 1832 Reforms.
