Founded in 1877, the OJ Club's mission is to uphold the lasting bonds and camaraderie between former pupils of Hurstpierpoint College. As the oldest continuously running school alumni association in the UK, the Club traces its history back to the founding of Hurst itself in 1849, and every Hurst alumnus becomes a member automatically.

Today the OJ Club reaches OJs across the world, from recent leavers to those decades out of Hurst. A broad range of societies, sporting, professional and social, sit at the heart of the Club, giving OJs of every generation the chance to reconnect. The Club also offers a full calendar of events, including reunions, dinners and socials, alongside the annual Foundation Magazine, Floreat.
