Allasdale (Scottish Gaelic: Athalasdal, pronounced [ˈa.əl̪ˠəs̪t̪əl̪ˠ]) is a settlement on Barra in the Outer Hebrides, Scotland.

The settlement is also within the parish of Barra,[1] and is situated on the A888 which is the island's circular main road.

[2] In May 2007 Channel 4's archaeological television programme Time Team investigated some prehistoric remains that had first been partly exposed when storms in October 2005 had blown away some sand dunes.

The site had been previously investigated in 2006 by a rescue survey funded by Historic Scotland.

[3] The programme featuring Allasdale was first broadcast on 20 January 2008, as part of Series 15 of Time Team.
