You built relationships and found communities at Harvard—and as part of the alumni community, you can make those same connections. With Harvard Alumni Association Shared Interest Groups (SIGs), no matter what you’re interested in, chances are, there’s a SIG waiting for you. SIGs are recognized communities of University-wide alumni who actively engage around a central unifying purpose, mission, background, or activity beyond class affiliation, school, or regional proximity.

These mission-driven organizations are part of a neural network of alumni communities that also includes Harvard Clubs, school-based organizations, and College classes.
