The British Overseas Territories (BOTs) are the 14 territories with a constitutional and historical link with the United Kingdom that, while not forming part of the United Kingdom itself, are part of its sovereign territory. The permanently inhabited territories are delegated varying degrees of internal self-governance, with the United Kingdom retaining responsibility for defence, foreign relations and internal security, and ultimate responsibility for good governance. All of the territories are inhabited by civilians, except three that are chiefly or only inhabited by military or scientific personnel. All fourteen have the British monarch as head of state. These UK government responsibilities are assigned to various departments of the Foreign, Commonwealth and Development Office and are subject to change.

A dependent territory, dependent area, or dependency is a territory that does not possess full political independence or sovereignty as a sovereign state and remains politically outside the controlling state's integral area. As such, a dependent territory includes a range of non-integrated not fully to non-independent territory types, from associated states to non-self-governing territories.
