Mingulay is the second largest of the Bishop's Isles in the Outer Hebrides of Scotland. Located 12 nautical miles south of Barra, it is known for an extensive Gaelic oral tradition incorporating folklore, song and stories and its important seabird populations, including puffins, black-legged kittiwakes, and razorbills, which nest in the sea-cliffs, amongst the highest in the British Isles.

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.
