Shillay (Scottish Gaelic: Siolaigh) is an uninhabited island which lies 2 km north of Pabbay in the Outer Hebrides of Scotland.
The name is derived from the Norse selr-øy meaning seal island and is a Scottish Wildlife Trust reserve owing to its international importance for breeding grey seals.
There is no record or evidence that it has ever seen human habitation.
