Shared Interest Group Meetups
Following the Harvard Alumni Day Yard party, many HAA Shared Interest Groups host meetup events—all are welcome to attend.
Harvard Alumni Association (HAA) Shared Interest Groups (SIGs) bring together a global network of alumni who share your interests, professions, and passions. United around common themes and areas of interest, these vibrant communities offer meaningful opportunities to connect within the Harvard alumni network.
Following the Harvard Alumni Day Yard party, many of these groups host meetup events on campus, held from 3:00–5:00 p.m. on Alumni Day. These convenings provide a chance to engage with fellow alumni and current SIG members. All alumni from across the University are welcome to attend.
