Harvard and Radcliffe College Reunions

Celebrate your next milestone reunion with us!

Beginning with your 5th Reunion, you and your entire Harvard and Radcliffe College Class are invited back to campus every five years to celebrate the place and community you once called home.

No matter where your life has taken you since you last walked through the gates of Harvard Yard, every Reunion provides the opportunity to have all your College friends together in one place, to see classmates with whom you’ve lost touch, to relive your days as a student, and to celebrate your Class alongside family and friends. It’s a highlight of the alumni calendar each year for a reason!

We are excited to welcome Harvard and Radcliffe College Classes ending in 5 or 0 back to Cambridge next spring! Please check back soon for additional information about your reunion.

Save the Date!

All College Classes ending in 5 or 0 are officially in Reunion and invited to campus spring 2025. We are looking forward to welcoming you back to Cambridge!
