2018 Alpine Skiing World Cup – Women's slalom

The women's slalom in the 2018 FIS Alpine Skiing World Cup involved 12 events, including three parallel races (one parallel slalom and two city events) and the season finale in Åre, Sweden.

Defending champion Mikaela Shiffrin from the United States won nine of the twelve races for the season (seven of the nine slaloms and two of the three parallel races); this was Shiffrin's fifth discipline championship in slalom.

The season was interrupted by the 2018 Winter Olympics from 12-24 February 2018 at Yongpyong Alpine Centre (slalom and giant slalom) at the Alpensia Sports Park in PyeongChang and at the Jeongseon Alpine Centre (speed events) in Jeongseon, South Korea. The women's slalom was held on 22 February.
