Loch Tummel (Scottish Gaelic: Loch Teimheil) is a long, narrow loch, seven kilometres (4+1⁄2 miles) northwest of Pitlochry in the council area of Perth and Kinross, Scotland.
It is fed and drained by the River Tummel, which flows into the River Tay.
The loch is traversed by roads to both north and south. Along the northern side the road is numbered as the B8019, and runs from the Pass of Killiecrankie on the A9 in the east to Tummel Bridge at the head of the loch. The road on the southern side is unclassified, and meets the A9 further south, near to Pitlochry.
