Montgomeryshire (Welsh: Sir Drefaldwyn) was a constituency^{[n 1]} in Wales represented in the House of Commons of the UK Parliament.

Created in 1542, it elected one Member of Parliament (MP), formerly known as the knight of the shire, by the first-past-the-post system of election. It was abolished following the 2023 Periodic Review of Westminster constituencies prior to the 2024 general election.

The Montgomeryshire Senedd constituency was created with the same boundaries in 1999 (as an Assembly constituency).
