Kinross and Western (or West) Perthshire was a county constituency of the House of Commons of the Parliament of the United Kingdom from 1918 until 1983, representing, at any one time, a seat for one Member of Parliament (MP), elected by the first past the post system of election.

The constituency was first defined by the Representation of the People Act 1918, and first used in the 1918 general election, as one of two county constituencies covering the county of Kinross and the county of Perth. The other was the Perth constituency.

Prior to the 1918 election the county of Kinross was covered, nominally, by Clackmannanshire and Kinross-shire, which also covered, nominally, the county of Clackmannan, and the county of Perth was covered, nominally, by Eastern Perthshire, Perth (as a burgh constituency) and Western Perthshire. Constituency boundaries were defined in terms of the Representation of the People (Scotland) Act 1832 and the Redistribution of Seats Act 1885 and, by these terms, five detached parishes of the county of Perth and one detached parish of the county of Stirling were within the Clackmannanshire and Kinross-shire constituency. Also, by 1918, for local government purposes, under legislation dating from 1889, county boundaries throughout most of Scotland had been redrawn, and detached parishes had become generally historic.
