The United Nations Peacekeeping Force in Cyprus (UNFICYP) is a United Nations peacekeeping force that was established under United Nations Security Council Resolution 186 in 1964 to prevent a recurrence of fighting following intercommunal violence between the Greek Cypriots and Turkish Cypriots, to contribute to the maintenance and restoration of law and order and to facilitate a return to normal conditions. Major General Ingrid Gjerde is the current Force Commander of UNFICYP, appointed in 2021, and preceded by Cheryl Pearce (Australia). Assistant Police Commissioner Satu Koivu (Finland) is the current Senior Police Adviser appointed in 2021.

Peacekeeping by the United Nations is a role of the UN's Department of Peace Operations as an "instrument developed by the organization as a way to help countries torn by conflict to create the conditions for lasting peace". It is distinguished from peacebuilding, peacemaking, and peace enforcement although the United Nations does acknowledge that all activities are "mutually reinforcing" and that overlap between them is frequent in practice.
