Dwyfor Meirionnydd is a constituency of the House of Commons of the Parliament of the United Kingdom (at Westminster). The seat is bordered to the north by Bangor Abercony, to the south by Montgomeryshire and Glyndŵr, and to the east by Clwyd East. Until 2024, the seat shared the same boundaries with the Dwyfor Meirionnydd Welsh Assembly constituency, the latter of which still uses the borders established for the 2007 Welsh Assembly election.

Like its predecessors, it is a Plaid Cymru stronghold, with their candidate in 2019 achieving a majority of 15.9%.
