(Scottish Gaelic: Lag an Ratha - 'Hollow of the [Earth-Walled] Fort/Enclosure') is a village and parish in Atholl, Scotland.

It is situated at the confluence of the rivers Tay and Tummel, 500 metres (1⁄4 mile) west of the A9 road in Perth and Kinross.

Above the village is the site of a major early royal castle, perhaps the 'rath' of the place-name, still marked by a large ditch.

The ancient promontory fort is marked by a huge 'Celtic' cross, a monument to the 6th Duke of Atholl (1814–1864).
