The 2012–13 Sheffield Shield season marked the 121st edition of Australia's premier domestic first-class cricket competition. Six teams participated in the tournament, facing off in a double round-robin format to determine the winner.
Tasmania secured its third title in the competition, finishing the season as champions. The race for the final was notably tight, as every one of the six participating teams maintained a mathematical chance of qualifying heading into the last round of regular-season fixtures.
Ricky Ponting dominated the batting charts for Tasmania, finishing the tournament with 911 runs. His consistent performance throughout the season earned him the title of player of the series. Meanwhile, South Australia bowler Chadd Sayers topped the wicket-taking list, claiming 48 victims across the campaign.
