The Ugnayan ng Pahinungód/ Oblation Corps is a program of the University that institutionalizes volunteerism among UP constituents through the rendering of free services to communities in greatest need. It enjoins faculty, students, alumni, and employees of UP to share their skills and talents with our less privileged countrymen. It seeks to put flesh and blood to the term Iskolar ng Bayan.

Established in 1994 under the administration of then UP President Emil Q. Javier, the Ugnayan ng Pahinungód is presently existing in most autonomous units of the University of the Philippines. In UP Manila, it is currently under the directorship of Dr. Eric S.M. Talens.

Among those who have taken the rein of leadership of the volunteer program were Prof. Fatima Alvarez-Castillo, Dr. Mario de Villa, Dr. Carmencita Padilla, Dr. Juan Pablo Nañagas, and Dr. Froilan Inocencio.

To date, the Ugnayan ng Pahinungód Manila has already served communities from Aparri to Jolo benefiting more than 222,026 Filipinos through its various volunteer programs.
