Which Scottish archipelago includes Skye, Mull, and Islay?

The Scottish archipelago that includes Skye, Mull, and Islay is the Inner Hebrides.

The Inner Hebrides lie off Scotland's west coast, generally east and southeast of the Outer Hebrides. They include more than 30 inhabited islands, with Skye, Mull, and Islay among the largest and most populous. Other notable islands include Jura, Rùm, Tiree, and Iona.

The islands have a layered Gaelic, Norse, and Scottish history. The southern group is closely associated with Argyll and the medieval kingdom of Dál Riata, while many island names preserve Old Norse elements from the period of Norse influence. Scottish Gaelic remains part of the cultural life of several communities.

The main mix-up is geographic: the Inner and Outer Hebrides together form the Hebrides, but they are separate island groups. The Inner Hebrides are nearer mainland Scotland; the Outer Hebrides lie farther west across the Minch and related sea channels.
