The 2017–18 Sydney Sixers Women's season was the third in the team's history. Coached by Ben Sawyer and captained by Ellyse Perry, the Sixers entered WBBL|03 as the defending champions. They finished the regular season on top of the points table for the second season in a row and proceeded to reach a third-consecutive championship decider.
In the final, the Sixers claimed back-to-back titles with a comfortable nine-wicket defeat of the Perth Scorchers at Adelaide Oval, during which Sarah Coyte punctuated an emphatic return to top-level domestic cricket by claiming figures of 4/17 and earning Player of the Match honours.
