Amin Hassan Nasser (born 1960) is a prominent Saudi Arabian business executive and engineer who has served as President and CEO of Saudi Aramco since 2015. He earned a Bachelor of Science in industrial engineering from King Fahd University of Petroleum and Minerals in 1982, laying the foundation for a career deeply embedded in the oil and gas sector. Nasser's early professional journey began at Saudi Aramco, where he held various technical and managerial roles in refining, marketing, and upstream operations over more than three decades. In May 2015, he was appointed as acting president and CEO before assuming the role permanently in September 2015. Under his leadership, Aramco has pursued aggressive expansion in oil production capacity and invested heavily in petrochemicals and refining, while navigating global energy transitions. Nasser reports to Saudi Crown Prince Mohammed bin Salman, who oversees the company's strategic direction as part of Vision 2030 economic diversification efforts. He has been vocal in defending the fossil fuel industry, criticizing divestment campaigns and advocating for continued investment in oil amid shifting global demands toward renewables. His tenure has coincided with Aramco's record valuation, including a landmark IPO in 2019, solidifying his influence in international energy markets and Saudi Arabia's economic landscape.
