The Turkistan Islamic Party (TIP) (Arabic: الحزب الإسلامي التركستاني‎, romanized: al-Ḥizb al-Islāmī al-Turkistānī; Uighur: تۈركىستان ئىسلام پارتىيىسى, romanized: Türkistan Islam Partiyisi; Turkish: Türkistan İslam Partisi) or the Turkistan Islamic Movement (TIM), formerly known as the East Turkestan Islamic Movement (ETIM) and other names, is an Uyghur Islamic extremist organization founded in Western China. Its stated goals are to establish an independent state called East Turkestan replacing Xinjiang. The UN Security Council Al-Qaida Sanctions Committee has listed ETIM as a terrorist organization since 2002, though the United States removed it from its list of Terrorist Organizations in 2020.

Influenced by the success of the Afghan mujahideen against the Soviets in the Soviet–Afghan War, the TIP became prominent in 1990 during the Baren Township riot. The conflict took the form of a jihad which envisioned a similar result to the earlier creation of the First East Turkestan Republic (1933-1934). Their slogans contained anti-Communist rhetoric and calls for uniting Turks, indicating a movement akin to Islamic pan-Turkism historically congruent with southern Xinjiang rather than pure, radical Salafi jihadism or religious extremism. The revolt lasted several days and was put down by the Chinese government, which deployed significant forces to suppress the insurrection. The Chinese government viewed them as a jihadist movement akin to the mujahideen in Afghanistan across the border which gave birth to more radical movements such as the Party of Allah and the Islamic Movement of East Turkistan.

The Syrian branch of the TIP is active in the Syrian Civil War; they are largely grouped in Idlib well organized, battle-hardened and have been instrumental in ground offensives against President Bashar al-Assad's forces in Idlib and other Syrian northern regions.
