Daniel Pipes (born September 9, 1949, in Boston, Massachusetts) is an American historian, author, foreign policy analyst, Middle East scholar, and conservative political commentator. The son of Cold War historian Richard Pipes, he earned both his undergraduate and doctoral degrees in history from Harvard University, specializing in medieval Islamic history. Pipes has held academic positions at Harvard and the University of Chicago before transitioning to public commentary and activism.

He is the founder and president of the Middle East Forum (MEF), a conservative, often described as neoconservative, think tank and advocacy group established in 1990 that focuses on Middle East policy, promoting American interests in the region, pro-Israel advocacy, countering Islamist ideologies, supporting counter-jihad efforts, and advancing democracy in the Middle East. Pipes also founded Campus Watch and co-founded MEMRI. He serves as publisher of MEF's journal, Middle East Quarterly.

Known for his hawkish neoconservative views on Islam, the Middle East, and the Israeli-Palestinian conflict, Pipes strongly supports Israel and is critical of political Islam and Islamist movements. He frequently critiques Middle East studies scholars and has spoken at events such as those organized by the Israel on Campus Coalition. Pipes has authored books including Israel Victory: How Zionists Win Acceptance and written columns for publications like The Washington Times. While some critics label him an anti-Muslim activist, Pipes emphasizes his focus is on militant Islam rather than Muslims broadly.

Throughout his career, Pipes has influenced U.S. policy debates, contributed to discussions on Turkey, the liberal-conservative divide, and strategies for countering extremism, and developed networks advocating robust Western engagement in the Middle East. His work includes notable collaborations and sponsorships involving figures such as major donor Nina Rosenwald and support from David Horowitz.
