West (or Western) Perthshire was a county constituency of the House of Commons of the Parliament of the United Kingdom from 1885 to 1918. It elected one Member of Parliament (MP) by the first-past-the-post voting system.

The constituency was defined by the Redistribution of Seats Act 1885, by dividing the Perthshire constituency to form two new constituencies which were first used in the 1885 general election. The other new constituency was East Perthshire. Together with the burgh constituency of Perth, which was unaltered, these constituencies covered the county of Perth, except that five detached parishes had been merged into the Clackmannanshire and Kinross-shire constituency by the Representation of the People (Scotland) Act 1832.

As defined in the 1885 Act, the constituency consisted of the "Parishes of Aberfoyle, Ardoch, Auchterarder, Blair-Athole, Balquhidder, Blackford, Crieff, Comrie, Callander, Dunkeld and Dowally (except so much as is comprised in Division No. 1 as herein described), Dunblane, Dull, Fortingall, Fowlis Wester, Glendevon, Kenmore, Killin, Kilmadock, Kincardine, Kippen (except the detached part locally situate in Stirlingshire), Kirkmichael, Little Dunkeld, Logierait, Lecropt, Moulin, Madderty, Monzie, Monzievaird and Strowan, Muthill, Port of Menteith, Trinity Gask, and Weem."
