Strathallan is the strath of the Allan Water in Scotland. The strath stretches north and north-east from Stirling through Bridge of Allan, Dunblane and Blackford to Auchterarder in Perth and Kinross. Strathallan is also the name for one of the wards in the Perth and Kinross Council area, electing three councillors under the Single Transferable Vote system. From 2015 Strathallan Castle, traditional seat of the Viscount Strathallan, will be the new home of the T in the Park music festival which was forced to move from its current site at Balado airfield due to safety concerns. The 2015 T in the Park festival takes place from July 9–12, 2015. The main A9 road from central Scotland to the north of the country runs the length of Strathallan, as does the former Caledonian Railway line from Stirling to Perth and beyond.
Strathallan School, an independent boarding and day school, was originally located in Bridge of Allan but relocated away from the area to Forgandenny, Perth in 1920.
