You built relationships and found communities at Harvard—and as part of the alumni community, you can make those same connections. Shared Interest Groups (SIGs) are recognized communities of University-wide alumni who actively engage beyond class affiliation, school, or regional proximity.

Shared Interest Groups are part of a network of alumni communities that also includes Harvard Clubs, school-based organizations, and College classes.

We currently are not accepting applications for new SIGs as we are processing outstanding requests and supporting newly approved SIGs. Please revisit this page in 2025.
