Devizes /dɪvaɪzɪz/ is a constituency^{[n 1]} in Wiltshire, England, represented in the House of Commons of the UK Parliament since 2019 by Danny Kruger, a Conservative.^{[n 2]}

The constituency includes four towns and many villages in the middle and east of the county. The area's representative has been a Conservative since 1924.

Further to the completion of the 2023 Periodic Review of Westminster constituencies, the seat will be subject to boundary changes which entail the loss of the town of Devizes to the newly created constituency of Melksham and Devizes. As a consequence, it will be renamed East Wiltshire, to be first contested at the next general election.^[2][3]

Until 1885 Devizes was a parliamentary borough, electing two Members of Parliament (MPs) by the bloc vote system until the 1868 election, when the Reform Act 1867 reduced its representation to one MP, elected by the first-past-the-post system of election. The Redistribution of Seats Act 1885 abolished the parliamentary borough, and created a new county constituency of the same name, covering a wider area and electing one member. It has returned a Conservative MP at every election since 1924.

Its most notable MP was Henry Addington, who held the seat during his term as Prime Minister, as well as when he was Speaker of the House of Commons.
