A constituent state, constituent entity, or constituent part, is a territorial and constitutional entity forming part of a sovereign state. A constituent state holds administrative jurisdiction over a defined geographic territory and is a form of regional government.

Constituent entities united in a federal union under a federal government are more specifically known as federated states.

Administrative units that are not federated but enjoy a greater degree of autonomy or self-government than others within the same country can be considered constituent states of a larger sovereign state. This relationship is called a federacy.Autonomous republics like Karakalpakstan in Uzbekistan and Crimea in Ukraine are examples.

States existing in free association with another can be considered constituent states of a sovereign entity. For example, the Cook Islands, New Zealand and Niue constitute the three constituent entities of the Realm of New Zealand, united under a single head of state, which is the Queen of New Zealand.
