John Michael Kumleben (26 May 1933 – 21 June 2014) was a South African cricketer who played first-class cricket for Oxford University and Orange Free State between 1956 and 1961. John Kumleben attended Michaelhouse and the University of Cape Town before going on to University College, Oxford, where he studied law. He won a hockey blue at Oxford, but although he played several matches for the university cricket team he did not win a cricket blue. His highest score was 100, made out of a team total of 196, after Oxford followed on against Yorkshire in 1957; he and Christopher Melville added 76 in 50 minutes for the last wicket but were unable to avert an innings defeat.
