The 1989 State of Origin series was the eighth time the annual three-game series between New South Wales and Queensland was contested entirely under 'state of origin' selection rules. It was Queensland's second consecutive Origin clean-sweep and an unpleasant inauguration for New South Wales' new coach Jack Gibson who, along with a new captain in Gavin Miller and eight new players, was brought into a dramatically overhauled Blues side that had lost its five last State of Origin matches.
