Prefecture de Police

The Préfet de Police is an official of the Government of France who supervises police and emergency services to Paris and the surrounding eight departments of Hauts-de-Seine, Seine-Saint-Denis, Seine-et-Marne, Val-de-Marne, Essonne, Yvelines and Val d'Oise, and has other security duties in the wider Île-de-France région.

The actual city of Paris is both a commune and a département. As it is the capital of France, with government assemblies and offices and foreign embassies, it poses special issues of security and public order. Consequently, the national government has been responsible for providing law enforcement and emergency services since the Paris Commune of 1871. This means that Paris does not have its own police municipale and that the Police Nationale provides these services directly as a subdivision of France's Ministry of the Interior.
