Thorney is a village about 8 miles (13 km) east of Peterborough in the City of Peterborough unitary authority, England, on the A47. Historically it was part of the Isle of Ely, which was considered part of Cambridgeshire but was transferred into the former county of Huntingdon and Peterborough and remained part of the Peterborough district into the transfer to Cambridgeshire and when it became a unitary authority in 1998. The A47 bypass opened in Winter 2005. The opening of the bypass has made the village much quieter.
