Argyll and Bute was a county constituency of the House of Commons of the Parliament of the United Kingdom.

It was created for the 1983 general election, merging most of Argyll with some of Bute and Northern Ayrshire, and then superseded by Argyll, Bute and South Lochaber in the 2023 Periodic Review of Westminster constituencies.

When created in 1983, the constituency covered the area of the Argyll and Bute district of the Strathclyde region.

In 2005 it was enlarged to cover the Argyll and Bute council area, which had been created in 1996.

The equivalent seat to Argyll and Bute in the Scottish Parliament was lost to the SNP in 2007, with Labour representing the overlapping constituency of Dumbarton to the southeast covering Helensburgh and Lomond.
