William C. Daroff (born 1968) is an American lawyer, lobbyist, and prominent leader in Jewish advocacy organizations. He has built a career focused on pro-Israel policy and combating antisemitism, serving in key roles within Republican politics and Jewish communal leadership. Daroff graduated from the University of Florida with a Bachelor of Arts in political science in 1990 and earned his Juris Doctor from the University of Florida Levin College of Law in 1993. Early in his career, he worked as a legislative aide in the Ohio State Senate and later as executive director of the Republican Jewish Coalition's Midwestern office, before advancing to national leadership positions in advocacy. He succeeded Malcolm Hoenlein as the CEO of the Conference of Presidents of Major American Jewish Organizations on February 1, 2020, an umbrella group representing over 50 major U.S. Jewish organizations dedicated to coordinating pro-Israel advocacy, strengthening U.S.-Israel relations, and addressing global Jewish concerns. In this role, he has navigated complex geopolitical issues, including efforts to maintain bipartisan support for Israel amid rising antisemitism and international tensions. Prior to this, he served as the director of the Washington office for the Republican Jewish Coalition and as senior vice president of the Conference of Presidents, where he honed his expertise in federal lobbying and coalition-building. Daroff is recognized for his influence in networks connecting Jewish organizations, political leaders, and policymakers. He is affiliated with the Republican Party but emphasizes bipartisan approaches in his work. As a Jewish American, his efforts often intersect with broader discussions on ethnicity, religion, and foreign policy influence. No major legal controversies or scandals are publicly documented, though his advocacy work has drawn criticism from pro-Palestinian groups for its staunch pro-Israel stance.
