This is a list of all hat-tricks scored during FIFA Women's World Cups; that is, the occasions when a footballer has scored three or more goals in a single football World Cup match (not including FIFA Women's World Cup qualification matches).
So far, 27 hat-tricks have been scored in over 270 matches in the 9 editions of the World Cup tournament.
As FIFA is the governing body of association football, official hat-tricks are only noted when FIFA recognises that at least three goals were scored by one player in one match.
The first hat-trick was scored by Carolina Morace of Italy, playing against Chinese Taipei in the 1991 FIFA Women's World Cup; the most recent (as of 2 August 2023) was by Kadidiatou Diani of France, playing against Panama in the 2023 FIFA Women's World Cup.
The record number of hat-tricks in a single World Cup tournament is six, which occurred during the 2015 FIFA Women's World Cup in Canada, coinciding with the expansion of the tournament to 24 teams from 16.
