A Crown colony, also known in the 17th century as royal colony, was a type of colonial administration of the British overseas territories.

Crown, or royal, colonies were ruled by a governor appointed by the monarch. By the middle of the 19th century, the sovereign appointed royal governors on the advice of the Secretary of State for the Colonies. Under the name of "royal colony", the first of what would later become known as Crown colonies was the English Colony of Virginia in the present-day United States, after the Crown, in 1624, revoked the royal charter it had granted to the Virginia Company, taking over direct administration.

Until the mid-19th century, the term "Crown colony" was primarily used to refer to those colonies that had been acquired through wars, such as Trinidad and Tobago and British Guiana, but after that time it was more broadly applied to any colony other than the Presidencies and provinces of British India and the colonies of settlement, such as The Canadas, Newfoundland, British Columbia, New South Wales, Queensland, South Australia, Tasmania, Victoria, Western Australia, and New Zealand, later to become the Dominions.
