The Sayeret Matkal (Hebrew: סיירת מטכ״ל) (formerly Unit 269 or Unit 262) (English: General Staff Reconnaissance Unit) is an elite special reconnaissance unit of the Israel Defense Forces (IDF). It is subordinate to the General Staff of IDF.

Though primarily a field intelligence-gathering unit, conducting deep reconnaissance behind enemy lines to obtain strategic intelligence, Sayeret Matkal is also tasked with a wide variety of special operations, including black operations, combat search and rescue, counterterrorism, hostage rescue, HUMINT, irregular warfare, long-range penetration, conducting manhunts, and reconnaissance beyond Israel's borders.

While primarily subordinate to the General Staff, Sayeret Matkal is also the special operations component of the Military Intelligence Directorate (Aman). Its primary role is field intelligence-gathering and deep reconnaissance behind enemy lines, which aligns it closely with Aman's objectives.

The unit is modeled after the British Army's Special Air Service (SAS), taking the unit's motto "Who Dares Wins". The unit is the Israeli equivalent of the SAS.

In 1954, Israel's first special operations unit—Unit 101—was disbanded following the outcry provoked by the Qibya massacre. This left the IDF without a dedicated special-forces unit other than the Navy's Shayetet 13, a naval commando unit that could not fully replace Unit 101. In 1957, Major Avraham Arnan, a former yeshiva student and Palmach fighter, petitioned the IDF General Staff to create a unit that could be dispatched to enemy-held territory to carry out top secret intelligence-gathering missions. Arnan's idea (backed by David Ben-Gurion and Yitzhak Rabin) was to create a unit that would recruit only the best and the brightest of Israeli youth. Prospective fighters were to be hand-picked, being physically and intellectually the best soldiers available. Originally part of Aman's Unit 504, Sayeret Matkal began to operate independently a year later as the General Staff's special operations force, modeled after the British Special Air Service. Members of the unit were trained by Bedouin trackers to obtain a better understanding of their adversaries. Established a year after the formation of Israel's first helicopter squadron, the close co-operation between the two units allowed Sayeret Matkal to deploy longer and deeper inside Arab territory than its predecessor. Arnan's vision for Sayeret Matkal (of which he was the first commander) was of a unit that would carry out strategic intelligence-gathering and other operations; as such it would receive its missions only from the General Staff. Sayeret Matkal would also evaluate new weapons and doctrines that could influence the entire IDF.

In the first years of the unit, it was manned by Palmach veterans, veterans of the intelligence corps, veterans of Unit 101 and the paratroopers unit. Among them Isaac Shoshan, Yair Harari, Eli Gil ("Daud"), Sami Nachmias, Charles Levy ("Salem"), Moshe Levin (Kukala), Shmuel Ben Zvi (Shemil), Yitzhak Ghibli ("The Little One"), Yehiel Amsalem – the commander of the first team in the unit, Meir Har-Zion, Avshalom Adam, Aharon Eshel, Micah Kapusta, Rami Kafkafi and many other young people from kibbutzim.

Its first operational activity was carried out in a dedicated assignment in Lebanon in May 1962. The success of this mission paved the way for the unit's second operation five months later in Syria. In the early 1960s, Sayeret Matkal conducted several intelligence-gathering operations in the Sinai Peninsula—the last of which was launched just four months before the outbreak of the Six-Day War. But, due to the extensive training, planning and preparation that had to be undertaken before its missions, Sayeret Matkal ended up not seeing any action during the war itself. It was however engaged extensively in the following War of Attrition. After 1967, with the rise of Arab terrorism perpetrated by groups such as the Palestine Liberation Organization (PLO), Sayeret Matkal began developing the first counterterrorism and hostage rescue techniques in the world. Beginning with Operation Isotope, the unit carried out several high-profile operations that thrust it into the limelight as an "elite paratroopers" unit (Sayeret Matkal's existence was classified at the time). In 1972, during the Munich Olympic hostage crisis, it was reported that Mossad head Zvi Zamir offered the assistance of Sayeret Matkal for the hostage rescue. However, the West German government rejected the offer, insisting that the Bavarian State Police would handle the crisis. In the subsequent Mossad assassinations following the Munich massacre, Sayeret Matkal struck the PLO in Beirut.

The Yom Kippur War in 1973 brought a profound change to the unit. With Israel fighting on two fronts and the General Staff busy with managing the war, Sayeret Matkal found itself without missions to perform. Sayeret Matkal officers then split into two camps: those who believed that the unit should be kept in reserve and not be lightly sent to missions where it could endure heavy casualties, and those that wanted to go into action, even if that meant missions with little planning and more akin to a commando force than to the strategic-oriented Sayeret Matkal. The latter prevailed and Sayeret Matkal was tasked with operations on both fronts. After the war, Sayeret Matkal began developing plans for wartime in advance, so that when war came, the unit could go into action immediately, without waiting for the General Staff's orders and missions. A reserve company of Sayeret Matkal was also designated specifically for cooperation with the Israeli Air Force, shown by the war to be lacking. This would later evolve into the Shaldag Unit.
