Potheridge (alias Great Potheridge, Poderigge, Poderidge or Powdrich) is a former Domesday Book estate in the parish of Merton, in the historic hundred of Shebbear, 3 miles south-east of Great Torrington, Devon, England. It is the site of a former grand mansion house re-built by George Monck, 1st Duke of Albemarle (1608–1670) circa 1660 on the site of the former manor house occupied by his family since at the latest 1287. It was mostly demolished in 1734 after the death of the widow of his son Christopher Monck, 2nd Duke of Albemarle (died 1688).
