D mitry Mazepin is a Russian oligarch who built his fortune in the chemical and fertilizer industry. He is the founder and was the controlling shareholder of Uralchem, one of Russia's largest producers of mineral fertilizers. After working in various business and state-owned enterprises, he began consolidating control over chemical plants in the early 2000s.

He built Uralchem into a major global player in the fertilizer market. He also acquired a significant stake in Uralkali, one of the world's largest potash producers, further solidifying his position as a dominant figure in the industry. He gained some international prominence as the father of former Formula One driver Nikita Mazepin, and he was the title sponsor of the Haas F1 team. Due to his close ties to the Kremlin, Mazepin was hit with heavy sanctions by the European Union, the United Kingdom, and other countries following Russia's 2022 invasion of Ukraine, forcing him to reduce his stake in his companies.
