EKO Cobra (Austrian German: Einsatzkommando Cobra; "Special Intervention Unit Cobra") is a police tactical unit of the Austrian Federal Ministry of the Interior. EKO Cobra is not part of the Austrian Federal Police, but instead is part of the Directorate for Special Units/Special Intervention Unit Cobra (Austrian German: Direktion für Spezialeinheiten/Einsatzkommando Cobra, DSE). The DSE reports to the Directorate General for Public Security (GD).

The unit's missions primarily involve anti-irregular military, apprehension of armed and dangerous criminals, counterterrorism and hostage rescue crisis management, executive protection, high-risk tactical law enforcement situations, operating in difficult to access terrain, protecting high-level meeting areas, providing security in locations at risk of attack or terrorism, special reconnaissance in difficult to access and dangerous areas, support crowd control and riot control, and tactical special operations.

The roots of the EKO Cobra lie in the Gendarmerieeinsatzkommando Bad Vöslau that was originally formed by the regional police authority of Lower Austria to protect East European Jews during their migration via Austria to Israel against terrorist threats. As the tactical skills of this unit were welcome in other fields, too, the mission of the Gendarmerieeinsatzkommando became broader in the course of years, and it climbed the hierarchy, from being a regional unit to becoming assigned directly to the Generaldirektion für öffentliche Sicherheit, the leading authority for public security within the Ministry of the Interior.

The name Cobra was coined by the press. It was a reference to the US TV series Mission: Impossible, which was aired in German under the title Kobra, übernehmen Sie. It first appeared in June 1973 in the Kronen Zeitung.

The determining step of founding today's Cobra as a unit of the Ministry of the Interior rather than a regional police unit was done in 1978, primarily as a response to the Munich massacre attack on Israeli athletes at the 1972 Munich Olympics. Its main office is in Wiener Neustadt, with sub-offices in Graz, Linz, Salzburg, and Innsbruck. GSG-9 and Sayeret Matkal trained the first operators of the GEK.

The Federal Ministry of the Interior changed the unit's name from GEK to EKO Cobra in 2002.

EKO Cobra was involved in a hostage rescue in the Graz-Karlau Prison in 1996, and numerous other operations. Although it has never participated in the same type of hostage rescue operations that the HRT, GIGN, GIS, NSG, ERU, GSG 9, and the SAS have had, the EKO Cobra is the only Counter-Terrorism unit to end a hijacking while the aircraft was still in the air. On 17 October 1996, four Cobra officers were on board an Aeroflot Tupolev Tu-154 escorting deported prisoners to Lagos when a Nigerian man threatened the cockpit crew with a knife and demanded a diversion to Germany or South Africa. The team overpowered the man and handed him over to authorities after landing.

In the course of the 2006 Lebanon War EKO Cobra assisted in the evacuation of Austrians and other EU citizens from Lebanon.
