The OKS Golf Society is open to all members of the OKS Association. Formed in the 1950s, the society currently has over 100 members and enjoys a calendar of events during the year including Halford Hewitt, Grafton Morrish and the Gray Public Schools Competition. They also play a match against current pupils at King's, and against other alumni golf clubs.

Membership costs £25 per annum, payable by standing order on 1st April. This cost is levied to cover administration, entry to the Public Schools' Competitions and assistance for Young Golfers,* and minor subsidy for other members at specified meetings.
