The 2018–19 Sydney Sixers Women's season was the fourth in the team's history. Coached by Ben Sawyer, they finished the regular season of WBBL|04 on top of the ladder to claim their third-consecutive minor premiership while captain Ellyse Perry set a new Women's Big Bash League record for most runs in a single campaign and was named Player of the Tournament.
In the semi-finals, the Sixers won a "miracle" encounter against the Melbourne Renegades which was notable for a last-ball run out that forced the game into a super over. In the championship decider, the Sixers fell short of achieving a three-peat, losing a "classic" contest to the Brisbane Heat by three wickets.
