State police, provincial police or regional police are a type of sub-national territorial police force found in nations organized as federations, typically in North America, South Asia, and Oceania. These forces typically have jurisdiction over the relevant sub-national jurisdiction, and may cooperate in law enforcement activities with municipal or national police where either exist.
