A dependent territory is a territory that is not fully independent or sovereign. They belong to a sovereign state, and are dependent on that state to some degree. There are varying degrees and forms of such a dependence. They are commonly distinguished from subnational entities in that they are not considered to be part of the state. A subnational entity typically represents a division of the country proper, while a dependent territory is a legally separate territory that enjoys a greater degree of autonomy.

As an example, Greenland is a dependent territory of Denmark, and Saint Helena is a dependent territory of the United Kingdom.

Most of these dependent territories were originally colonies, which often had no autonomy.
