The Northern Syria Buffer Zone (also known as the Safe Zone, Peace Corridor, or Security Mechanism) was a temporary Syrian Civil War demilitarized zone (DMZ) established on the Syrian side of the Syria–Turkey border in August 2019 to maintain security along the border and to dissuade a prospective Turkish invasion of the self-proclaimed Autonomous Administration of North and East Syria.^[1] The DMZ was administered by the Kurdish-led Syrian Democratic Forces (SDF) and their military councils and enforced by United States Armed Forces and Turkish Armed Forces personnel.

The buffer zone collapsed in early October 2019, before it was fully implemented, when Turkey dismissed the agreement on 1 October and the United States abandoned the effort on 6 October after U.S. President Donald Trump ordered the withdrawal of U.S. forces from northern Syria, allowing for Turkish President Recep Tayyip Erdoğan's planned ground incursion into the region. The subsequent Turkish offensive on 9 October rendered the buffer zone fully obsolete.^[2]

The failed Turkish-U.S. arrangement was replaced on 22 October 2019 with the separate Second Northern Syria Buffer Zone, negotiated between Russia, Turkey and the Syrian government.
