The Harvard Alumni Association (HAA) is the official association for you and the more than 400,000 Harvard alumni around the world. You have a membership just by attending Harvard College or one of Harvard's Graduate and Professional Schools.

Here at the HAA, we connect you and your fellow graduates with a wealth of networking opportunities, professional development resources, programs, volunteer opportunities, faculty-led trips, and more. So, whether you are looking to build or expand your Harvard community, reconnect with classmates, mentor students, engage in lifelong learning, or stay informed on Harvard news—the HAA is here to keep you connected to it all.

You may no longer be a student, but Harvard and the HAA will always be here for you. Remember, Harvard’s alumni community is your community.
