Paul Joseph McNulty (born 1958) is an American attorney and former government official. He served as the United States Attorney for the Eastern District of Virginia from 2001 to 2006, a key role in the Bush administration's national security prosecutions, where he supervised major cases including the high-profile AIPAC espionage case. He later served as U.S. Deputy Attorney General from October 2005 to May 2007 under Attorney General Alberto Gonzales, overseeing major federal investigations. His tenure was marked by involvement in the controversial dismissal of several U.S. Attorneys in 2006, where he later testified before Congress, admitting to misleading statements about the political motivations behind the firings, which contributed to the scandal and led to his resignation.

Prior to his DOJ roles, McNulty had a career in Republican politics and law, serving as legislative aide and later Chief of Staff to U.S. Representative Frank Wolf (R-VA) from 1996 to 2001. He previously worked in the Reagan White House as an Assistant for Legislative Affairs from 1983 to 1985 and practiced law at firms including Miller, Cassidy, Larroca & Lewin. He earned a Bachelor of Arts from Grove City College in 1980 and a Juris Doctor from Washington and Lee University School of Law in 1983.

After leaving government service, he joined the faculty at Washington and Lee University School of Law as a visiting professor in 2007. In 2008, McNulty became the ninth president of Grove City College, a private Christian liberal arts college in Pennsylvania, serving until 2018. During his presidency, he focused on maintaining the institution's independence from federal funding and promoting its conservative values. He has since engaged in consulting, board memberships, and legal advisory roles, including serving on the board of the Alliance Defending Freedom. McNulty's career reflects a blend of legal expertise, Republican political involvement, and commitment to faith-based education.
