The Flannan Isles or the Seven Hunters are a small island group in the Outer Hebrides of Scotland, approximately 32 kilometres west of the Isle of Lewis. They may take their name from Saint Flannan, the 7th century Irish preacher and abbot.

The Outer Hebrides or Western Isles, sometimes known as the Long Isle or Long Island, is an island chain off the west coast of mainland Scotland. The islands are geographically coextensive with Comhairle nan Eilean Siar, one of the 32 unitary council areas of Scotland. They form part of the archipelago of the Hebrides, separated from the Scottish mainland and from the Inner Hebrides by the waters of the Minch, the Little Minch, and the Sea of the Hebrides.
