Easdale (Scottish Gaelic:Eilean Èisdeal) is one of the Slate Islands, in the Firth of Lorn, Scotland. Once the centre of the Scottish slate industry, there has been some recent island regeneration.

A ferry sails from Easdale to Ellenabeich (Gaelic: Eilean nam Beathach) on the nearby island of Seil (Gaelic: Saoil), which is separated from Easdale by only a narrow channel. Confusingly, Ellenabeich is sometimes known as Easdale as a result of its traditional connections with the island.
