Undergraduate-based Shared Interest Groups (SIGs) are alumni extensions of student clubs, bringing together graduates who share the activities, communities, and affinities they pursued on campus. 

Unlike regional Harvard Clubs and other Harvard Alumni Association (HAA) SIGs, undergraduate SIGs are closed communities whose membership is limited to alumni who participated in the corresponding student organization as undergraduates. 

Many of these groups focus on supporting the current student organization and its activities, helping to sustain traditions, programming, and mentorship across generations.

If you were a member and participated in any of the following organizations as an undergraduate student, you are invited to get involved by reaching out to the contacts listed or visiting their websites. If you are looking for a list of other non-undergraduate-based SIGs, visit the SIG Directory.
