The 2018 World Women's Curling Championship (branded as the 2018 Ford World Women's Curling Championship for sponsorship reasons) was held from March 17–25 at the North Bay Memorial Gardens in North Bay, Ontario, Canada. The format of the tournament was changed this year, with 13 teams qualifying for the tournament (as opposed to 12 in previous years), and the top 6 teams from round-robin play will qualify for the playoffs (rather than 4). The playoff system were single-knockout, where the top two teams received a bye while the remaining four played the first round.
