The Ministry of Citizen Protection (Greek: Υπουργείο Προστασίας του Πολίτη) is the government department responsible for Greece's public security services, i.e. the Hellenic Police, the Hellenic Fire Service, Hellenic (Corrections) Prison System, the Agrarian Police and the General Secretariat for Civil Protection.

On 7 October 2009, it was revived as the Ministry of Citizen Protection (Υπουργείο Προστασίας του Πολίτη) and was eventually renamed as the Ministry of Public Order and Citizen Protection on 21 June 2012.

Following the electoral victory of Syriza in January 2015, it was subordinated to the Ministry of the Interior and Administrative Reconstruction and was headed by an Alternate Minister (Αναπληρωτής Υπουργός).

The incumbent minister in the Second Cabinet of Kyriakos Mitsotakis is Michalis Chrisochoidis, a member of the Hellenic Parliament for the Athens B2 constituency with New Democracy.

Chrisochoidis has served in the role four times previously, as a member of PASOK and an independent politician.
