The 2018–19 FA Women's League Cup was the eighth edition of the FA Women's Super League and FA Women's Championship's league cup competition. It was sponsored by Continental AG, who sponsored the competition from its creation, and was officially known as the FA Continental Tyres League Cup. All 22 teams of the FA Women's Super League and FA Women's Championship contest the competition - the largest field in its history.
Arsenal were the defending champions; only they and Manchester City had won the cup in the previous seven seasons it was contested in.
Following the previous season's reversion to a group format in the initial stage, the 2018–19 WSL Cup kept the same format but expanded to accommodate the increase in teams in the top two divisions of women's football to 22. As a result, two of the four groups contained six teams while the others remained at five, with only the top two going through to the quarter-finals from each.[1]
