The HAA Crimson Society is the organization of all Harvard College and Radcliffe College alumni/ae starting the year after their 50th Reunion. The HAA Crimson Society Planning Committee plans an annual program inviting all non-reunion alumni/ae back to campus for festivities and programs to foster alumni/ae connections in the years between Harvard’s traditional milestone Reunions.
The HAA Crimson Society looks forward to welcoming all post-50th Reunion Harvard and Radcliffe College alumni/ae back to Cambridge in the Spring 2026!
