British Isles, group of islands off the northwestern coast of Europe. The group consists of two main islands, Great Britain and Ireland, and numerous smaller islands and island groups, including the Hebrides, the Shetland Islands, the Orkney Islands, the Isles of Scilly, and the Isle of Man. The Channel Islands are also sometimes included in this grouping.

Although the term British Isles has a long history of common usage in the English language, it is controversial, especially for those who argue the term communicates political and cultural connections between the republic of Ireland and the United Kingdom (the political entity consisting of England, Northern Ireland, Scotland, and Wales) that do not exist. This article uses the term British Isles as a geographical designation.

For accounts of the relationships between the peoples and states of Ireland and Great Britain across history, see Ireland: History, United Kingdom: History, England: History, Northern Ireland: History, Scotland: History, and Wales: History as well as articles on the smaller islands and island groups that make up the British Isles.
