Geoffrey Merton "Geoff" Griffin (12 June 1939 – 16 November 2006) was a Test cricketer who toured England with the South African cricket team in 1960, appearing in two Test matches. A right-arm, fast bowler and lower order batsman, his selection for the tour was controversial, because of his suspect bowling action – some of his deliveries were judged to be thrown rather than bowled. The core of his problem was that, due to a childhood accident, he was unable to fully straighten his right arm.
