Graduate alumni represent 30% of Princeton's alumni body and have degrees in a wide variety of disciplines. They are spread across the United States and throughout the world, with over 15% based internationally.

Graduate alumni are welcome and active participants in all Alumni Association programs, and also organize graduate-focused initiatives through the volunteer-driven Association of Princeton Graduate Alumni (APGA). Graduate Alumni Relations within the Office of Advancement provides support for the APGA, as well as additional programming geared toward providing opportunities for graduate alumni to reconnect with Princeton, their departments of study, fellow graduate alumni and current graduate students.
