Avdiivka Coke and Chemical Plant in Donetsk Oblast, Ukraine, was the largest coke producer in Ukraine and is owned by the company Metinvest, which is in turn owned by Rinat Akhmetov, a Ukrainian oligarch. AKHZ also produced a variety of chemicals including benzine, coal tar, coal oil ammonium sulphate and coke gas. The plant consisted of 13 main and 30 auxiliary workshops as well as service structural divisions.

The battle of Avdiivka was a major battle between the Russian and Ukrainian Armed Forces for control of Avdiivka, a city in Donetsk Oblast, during the Russian invasion of Ukraine. After more than a year and a half of intermittent fighting along the city's outskirts, Russian forces launched an offensive to capture Avdiivka on 10 October 2023, resulting in what was considered one of the bloodiest and fiercest battles of the war.
