East Devon is a constituency^{[n 1]} represented in the House of Commons of the UK Parliament since 2019 by Simon Jupp of the Conservative Party.^{[n 2]}

A report by the Electoral Reform Society found the seat (and its precursors) has been held by the Conservative Party since 1835, meaning it has been held for 186 years. This is currently the longest held seat by one party anywhere in the country.^[2]

The 2023 Periodic Review of Westminster constituencies proposes the seat be abolished, with the majority of the electorate, including Exmouth and Budleigh Salterton, being absorbed into Exmouth and Exeter East, to be first contested at the next general election. Sidmouth and Ottery St Mary will be included in the new seat of Honiton and Sidmouth.^[3][4]

1868–1885: The Hundreds of Axminster, Cliston, Colyton, East Budleigh, Exminster, Ottery St. Mary, Haytor, and Teignbridge, and Exeter Castle, and the parts of the hundred of Wonford that are not included in the city of Exeter.^[5]

1997–2010: The District of East Devon wards of Axminster Hamlets, Axminster Town, Beer, Budleigh Salterton, Colyton, Edenvale, Exmouth Brixington, Exmouth Halsdon, Exmouth Littleham Rural, Exmouth Littleham Urban, Exmouth Withycombe Raleigh, Exmouth Withycombe Urban, Lympstone, Newbridges, Newton Poppleford and Harpford, Raleigh, Seaton, Sidmouth Rural, Sidmouth Town, Sidmouth Woolbrook, Trinity, Upper Axe, Woodbury, and Yarty.

2010–present: The District of East Devon wards of Broadclyst, Budleigh, Clyst Valley, Exmouth Brixington, Exmouth Halsdon, Exmouth Littleham, Exmouth Town, Exmouth Withycombe Raleigh, Newton Poppleford and Harpford, Ottery St Mary Rural, Ottery St Mary Town, Raleigh, Sidmouth Rural, Sidmouth Sidford, Sidmouth Town, Whimple, and Woodbury and Lympstone, and the City of Exeter wards of St Loyes and Topsham.

The constituency is in the county of Devon, including eastern wards of Exeter, and has a shoreline on the Jurassic Coast.

Following a review of parliamentary representation in Devon by the Boundary Commission for England, which has increased the number of seats in the county from 11 to 12, East Devon was subject to significant boundary changes at the 2010 general election.^[6] In particular, the towns of Axminster and Seaton were transferred to the Tiverton and Honiton constituency. In addition, two wards from the City of Exeter are now part of the East Devon seat.

The main settlements in the constituency are the City Of Exeter Ward, St Loyes and neighbouring Topsham, the resorts of Exmouth, Budleigh Salterton and Sidmouth, and the inland towns of Ottery St Mary and Cranbrook.
