The National Intelligence Organization (Turkish: Millî İstihbarat Teşkilatı, MİT) is the state intelligence agency of Turkey.

Established in 1965 instead of the National Security Service, to gather information about the current and potential threats from inside and outside against all the elements that make up Turkey's indivisible integrity, constitutional order, existence, independence, security and national power, take precautions and take precautions when necessary.

The current headquarters of MIT is the KALE building in Ankara Etimesgut.

According to the former director of Foreign Operations, Yavuz Ataç, the military presence in the organization is negligible, although the organization has a military heritage. In 1990, the percentage of military personnel was 35%, while in 2007 the lower echelons were 4.5% military. Former deputy director Cevat Öneş said that the MİT suffered with each coup, as each military junta that took control of the organization had its own set of priorities.

While the organization has historically recruited from relatives of existing employees, the former director, Emre Taner, says that this is no longer the case. He is credited with reducing the turf war between the MİT and the General Directorate of Security as well as infighting inside the MİT itself. Taner announced a restructuring of the MİT at the start of 2009.

The MIT co-operates with the Central Intelligence Agency and the intelligence agencies of Russia. In addition, it has close communication and cooperation with the private Turkish security contractor SADAT International Defense Consultancy Inc. Its operations and missions are classified. In practice, religious minorities in Turkey are barred from careers in the MIT.
