Robert John Zadow (born 17 January 1954) is a former South Australian cricketer.
Zadow abandoned a promising Australian rules footballing career by moving to England in 1976 to play as an overseas amateur for Flowery Field Cricket Club in the Saddleworth and District League.
From 1979/80 he started to play regular first-class cricket for South Australia and was soon chosen to captain the side.
Notable innings include a century against the touring Indian side captained by Kapil Dev and at that time he was being mentioned in the Australian press as a possible Test candidate.
