Abdul Ali Mazari (Pashto: عبدالعلي مزاري, Dari:: عبدالعلی مزاری, 27 May 1946 – 13 March 1995), also known by his honorific title, Ustad, was an Afghan politician and leader of Hezbe Wahdat during and following the Soviet–Afghan War, who advocated for a federal system of governance in Afghanistan. Mazari envisioned that this would end the political and ethnic division in Afghanistan by guaranteeing rights to every ethnic group. He was allegedly captured and assassinated by the Taliban during negotiations in 1995 amid the Second Afghan Civil War.
In 2016, he was posthumously given the title "Martyr for National Unity of Afghanistan" and had a statue erected in his honor by the Islamic Republic of Afghanistan. Shortly after reclaiming power, the Taliban demolished the statue.
