Al-Tanf (Arabic: التَّنْف) is a U.S. military base in a part of the Rif Dimashq Governorate, Syria, which is controlled by the Syrian Free Army.^[3] It is located 24 km (15 mi) west of the al-Walid border crossing in the Syrian Desert. The surrounding deconfliction zone is located along the Iraq–Syria border and the Jordan–Syria border. The garrison is located along a critical road known as the M2 Baghdad–Damascus Highway. The Rukban refugee camp for internally displaced Syrians is located within the deconfliction zone.

A significant United States Armed Forces and allied European presence at the outpost began in early 2016 during the American-led intervention in the Syrian civil war in order to train anti-Islamic State fighters of the New Syrian Army armed opposition group, which was dissolved and reemerged as the Revolutionary Commando Army (Maghawir al-Thawra) in December 2016. As of 2025, the Al-Tanf base continues to serve as the headquarters for the Syrian Free Army and a contingent of at least 200 U.S. soldiers operating on behalf of the CJTF-OIR Coalition.
