2023 FIFA Women's World Cup Group B

Group B of the 2023 FIFA Women's World Cup was one of eight groups that formed the opening round of the tournament with the matches played from 20 to 31 July 2023. The group consisted of hosts Australia, the Republic of Ireland, Nigeria and Canada. The top two teams, Australia and Nigeria, advanced to the round of 16.

Canada became the first reigning Olympic champions to be eliminated in the subsequent Women's World Cup group stage. A win against Canada ensured Australia avoided a first group stage elimination since 2003, and following the elimination of fellow hosts New Zealand, assured every Women's World Cup up to 2023 had a host country participating in the knockouts. Nigeria progressed to the knockout stage for only the third time in their ninth Women's World Cup.

Discipline
Fair play points would have been used as tiebreakers in the group should the overall and head-to-head records of teams were tied. These were calculated based on yellow and red cards received in all group matches as follows:
 * first yellow card: minus 1 point;
 * indirect red card (second yellow card): minus 3 points;
 * direct red card: minus 4 points;
 * yellow card and direct red card: minus 5 points;

Only one of the above deductions was applied to a player in a single match.
