John Joseph DeGioia (born 1957) is an American academic administrator and philosopher who served as the president of Georgetown University from 2001 to 2024.

Having spent his entire career at Georgetown, where he received his undergraduate and graduate degrees, DeGioia was the dean of student affairs and held various vice presidential positions before becoming president.

[6] As dean of student affairs, he also was involved in the conflicts over Georgetown's Catholic identity during the tenure of Healy's successor, Leo J. O'Donovan.

[7] The funding for the group was later revoked due to three events that DeGioia claimed advocated for abortion, violating the terms he had set out for the club.

[8] O'Donovan named DeGioia the associate vice president and chief administrative officer of Georgetown's main campus in 1992.

[6] That same year, DeGioia was promoted to vice president, overseeing all operations of the main campus, including the university's finances, undergraduate admissions, financial aid, athletics, and student affairs.

[9] It was the board of directors' initial intention to hire a Jesuit for the job, but they determined that there was not a suitable candidate for the office.

In 2012, he publicly came to the defense of a student at the Georgetown University Law Center, Sandra Fluke, following her testimony before the U.S. House of Representatives in support of the Affordable Care Act's contraceptive mandate, when political pundit Rush Limbaugh made disparaging comments about her.

[18] That same year, DeGioia was criticized by prominent Catholics, including the Archbishop of Washington, Cardinal Donald Wuerl, for Georgetown's invitation of Kathleen Sebelius, the Secretary of Health and Human Services and author of the contraceptive mandate, to be honored as a graduation speaker.

[19] This prompted William Peter Blatty, a Georgetown alumnus, to file a canon lawsuit with the Vatican, requesting that it order the university to comply with Ex corde Ecclesiae.

He has been a member of the boards of directors of the Carnegie Corporation of New York and the National Association of Independent Schools, as well as a commissioner of the Knight Commission on Intercollegiate Athletics.

[28] Both Catholic,[29] they were married at Holy Trinity Church in the Georgetown neighborhood, in a ceremony presided over by DeGioia's uncle and Jesuit priest, John J.
