Francisco Alfafara Nemenzo Jr. (9 February 1935 – 19 December 2024) was a Filipino political scientist, educator, and activist who served as the 18th president of the University of the Philippines (UP) from 1999 to 2005.

He had previously served as chancellor of UP Visayas, UP Faculty Regent, and dean of the College of Arts & Sciences of UP Diliman.

[citation needed] Nemenzo was elected UP president against prominent competitors such as former senator Leticia Ramos-Shahani, former minister of economic planning Gerardo Sicat, and public administration pioneer and sociologist Ledivina V.

[9] His term was notable for the institutionalization of the Revised General Education Program (RGEP), comparable to the general education program of Harvard University and other American educational institutions, seeking to provide a holistic development of students through a free choice system of selecting courses in three divisions (Arts & Humanities, Social Science & Philosophy, and Mathematics, Science & Technology) to fit each student's intellectual pursuits.

In 2005, he stepped down as the University's highest official and was replaced by Emerlinda Roman of the College of Business Administration.
