Six-time women's world player of the year Marta has become the all-time leading scorer at a men's or women's World Cup finals.
The Brazilian legend netted a penalty in the Seleccao's 1-0 win over Italy to score her 17th World Cup goal - moving her ahead of the 16 goals scored by German striker Miroslav Klose and two clear of her compatriot Ronaldo.
Brazil's win puts them through to the knockout stages of the Women's World Cup in France.
Afterwards, Marta spoke of how she hopes breaking the record will help raise awareness regarding gender equality.
"The feeling is a joyful one, not only for breaking the record but for being able to represent women in doing so," she said.
"We are trying to represent women and show how women can play any type of role," she said.
"All the teams here, we are all representing [women]. Let me be clear, this is not only in sport.
"This is a struggle for equality across the board."
