Jack Gibson OAM (27 February 1929 – 9 May 2008) was an Australian rugby league coach, player, and commentator. He is widely considered one of the greatest coaches in the sport's history. Nicknamed 'Supercoach', he was highly regarded not only for his coaching record but also for his thirst for innovation, as he introduced new coaching and training methods into the sport in the 1970s, and 1980s, when first-grade rugby league was then still played and coached on a semi-professional basis.
