Harakat Nour al-Din al-Zenki was a Salafist rebel group in Syria that was formed in late 2011 during the Syrian Civil War. Named for Emir of Aleppo Nur ad-Din, the movement was formed in Aleppo to fight against the Syrian Arab Army, and it joined the Army of Mujahideen in the war against the Islamic State; the United States supplied the group with money during its war against ISIS and the government. In December 2014, it joined the Levant Front and also the Fatah Halab operations room. On 28 January 2017, its Idlib Governorate merged into the new Tahrir al-Sham organization, while its northern branch defected to the Sham Legion. On 20 June 2017, as the result of fighting between Tahrir al-Sham and Ahrar ash-Sham, the Nour al-Din al-Zenki movement split from Tahrir al-Sham. In 2017, the group had 7,000 fighters; by early 2019, however, the group was nearly destroyed by Tahrir al-Sham, and its remnants merged into the Syrian National Army. On 29 January 2025, the faction was merged into the new Syrian Army.
