Campaigh or Campay is a steep and rocky islet in outer Loch Ròg, Lewis, Scotland that lies north of Cealasaigh and Little Bernera.
A huge natural arch transverses the northern half of the island from south west to north east and there is a large sea cave to the south. The islet of Cùl Champaigh lies offshore to the north, and tiny Sgeir Dearg (red skerry) and the larger Màs Sgeir (seagull skerry) beyond.[1]
