Aymenn Jawad Al-Tamimi, born on January 1, 1996, is a British-Iraqi researcher, analyst, and historian specializing in jihadist groups, particularly the Islamic State of Iraq and the Levant (ISIL), its affiliates, and Middle Eastern insurgencies and conflicts, including the Syrian Civil War and the War in Iraq (2013–2017). He holds a BA in Classics from Brasenose College, Oxford University, obtained in 2017. He currently serves as a Research Fellow at the Middle East Media Research Institute (MEMRI) and as a fellow at the Middle East Forum. At MEMRI, he has collaborated professionally with figures like Steven Stalinsky, an Associate Fellow at the Middle East Forum, and an Independent Researcher and Analyst. Al-Tamimi is renowned for his detailed translations and analyses of extremist propaganda and ideological materials, providing insights that have been consulted by major media outlets including The New York Times, The Wall Street Journal, and The Washington Post, establishing him as a go-to expert on these topics.

In 2020, he co-authored a significant report for The New York Times in partnership with George Washington University as part of their 'The ISIS Files' series, offering in-depth analysis of ISIL's operations and ideology based on captured documents. His contributions extend to academic and journalistic circles, where he is recognized for his deep engagement with Arabic-language sources, enabling precise translations and contextual understanding of extremist narratives. However, Al-Tamimi has faced substantial criticism and controversy, including allegations of sympathies toward ISIL in his analyses, questionable conduct, and purported close relationships with ISIL fighters, sparking debates about his objectivity and potential biases in his research, though he maintains his work is purely analytical and no formal legal actions or investigations are documented.

Based in the United Kingdom, Al-Tamimi continues to contribute to discussions on counter-terrorism and Middle Eastern conflicts through publications and media appearances, positioning him within networks of influence focused on security and policy analysis. Despite his youth—he began publishing influential work in his late teens—his output has shaped public and policy discourse on global jihadism.
