Cronk edged out Storm teammate Cameron Smith, Brisbane's Darius Boyd and Cowboy Jason Taumalolo to be crowned the world's best rugby league player.
It is the first time in Cronk's career he has won the Golden Boot award and follows his second Dally M Player of the Year honour.
Cronk led his team to an NRL minor premiership, won the State of Origin series with Queensland and was named player of the tournament as Australia won the Four Nations in the UK.
