The 2018–19 Women's Big Bash League season or WBBL|04 was the fourth season of Women's Big Bash League, the semi-professional women'sTwenty20domestic cricket competition in Australia. The tournament ran from 1 December 2018 to 26 January 2019. Double-defending champions, the Sydney Sixers, ended the regular season on top of the ladder, while captainEllyse Perry broke the scoring record for a sole WBBL campaign and was named Player of the Tournament. In the two semi-finals at Drummoyne Oval on 19 January, the Brisbane Heat eliminated the Sydney Thunder before the Sydney Sixers knocked out the Melbourne Renegades. Both matches, notable for their "miracle" endings, were hailed as a showcase of "the irrefutable rise of women's cricket" and "sport with drama, skill and unpredictability – a potent recipe for success". In the final, also at Drummoyne Oval, the Heat caused an upset by defeating the Sixers with three wickets in hand and four balls remaining to claim their maiden title.

Teams
Each squad featured 15 active players, with an allowance of up to five marquee signings including a maximum of three from overseas. Under a new rule, Australian marquees were classed as players who held a national women's team contract at the time of signing on for their WBBL|04 team. This, combined with the introduction of two-year contracts ahead of the previous season, meant that the Sydney Sixers would inadvertently exceed their marquee player limit in 2018–19. To address this inequity, an injured or unavailable Sixers marquee could only be replaced by a domestic player.
