The British Islands is a term within the law of the United Kingdom which refers collectively to the following four polities:

These polities constitute the principal geopolitical and territorial nucleus of British sovereignty. Distinguished from the British Overseas Territories, which are remnants of the former British Empire, the British Islands represent the core legal and constitutional realm under the direct jurisdiction of The Crown and Parliament of the United Kingdom (i.e. United Kingdom proper), albeit with varying degrees of self-governance among the Crown Dependencies. A statutory definition of the term British Islands can be found in Schedule 1 of the Interpretation Act 1978.

The Isle of Man and the Bailiwicks of Guernsey and Jersey are Crown Dependencies and not part of the United Kingdom. Nevertheless, the Parliament of the United Kingdom may, on occasion, introduce legislation that is extended to these islands, typically through Orders in Council. As such, it has been found useful to have a collective term to encompass the combined territories. The phrase The United Kingdom and the Islands is employed in the Immigration Act 1971 to refer to this collective grouping.

In addition, while several categories of British nationality exist, only British citizens enjoy the automatic right of abode in the British Islands. Other British nationals, such as British Overseas Territories citizens, British Nationals (Overseas) and others, do not possess this right unless they separately acquire British citizenship or are granted immigration status such as indefinite leave to remain (ILR).
