Dumfriesshire, Clydesdale and Tweeddale is a constituency of the UK House of Commons, located in the South of Scotland, within the Dumfries and Galloway, South Lanarkshire and Scottish Borders council areas. It elects one Member of Parliament (MP) at least once every five years using the First-past-the-post system of voting. It is currently represented in Westminster by the former Secretary of State for Scotland, David Mundell, who has been the MP since 2005; from 2005 to 2017, he was the only Conservative MP in Scotland.

The seat has a diverse electoral history, with the Dumfriesshire area being a longtime Conservative seat, the Clydesdale area being formerly safe Labour territory, and Tweeddale had been part of Liberal Democrat-voting constituencies since the 1980s.
