Miles Barne (22 May 1746 – 8 September 1825) was a British Member of Parliament for Dunwich, a Pocket Borough in the county of Suffolk, between 1791 and 1796 and High Sheriff of Suffolk from 1790 to 1791. Barne's father had established himself as co-proprietor of the Borough and controlled one seat; on his father's death, Barne declined to fill the vacancy, and so it went to his younger brother instead. However, in 1791, his brother resigned and Barne reluctantly took up the seat, serving until 1796.
