Soay (Scottish Gaelic: Sòdhaigh, pronounced [ˈs̪ɔː.aj]) is an island just off the coast of Skye, in the Inner Hebrides of Scotland.

Unlike its neighbours Skye and Rùm, Soay is low-lying, reaching 141 metres (463 ft) at Beinn Bhreac.

The dumb-bell shaped island is virtually cut in half by inlets that form Soay Harbour (north) and the main bay, Camas nan Gall (to the south).

The island is part of the Cuillin Hills National Scenic Area, one of 40 in Scotland.

[2] Local stamps were issued for Soay between 1965 and 1967, all on the Europa theme, some being overprinted to commemorate Sir Winston Churchill.
