Perth and East Perthshire was a county constituency of the House of Commons of the Parliament of the United Kingdom from 1950 to 1983.
The constituency was defined by the House of Commons (Redistribution of Seats) Act 1949 and first used in the 1950 general election.
For the February 1974 general election, the results of the Second Periodical Review of the Boundary Commission were implemented, and there was a minor change to the boundaries of Perth and East Perthshire.
The burghs of Callander, Doune, and Dunblane in the county of Perth, the Perth parish of Muckhart and the Western district of the county (except the electoral division of Ardoch) had been merged into the Central region.
Constituencies defined to cover the Tayside region included Perth and Kinross.
