Marta scored her 15th career women's World Cup goal to become the all-time leader in tournament history, leading Brazil to a 2-0 win over South Korea in Montreal on Tuesday.
The five-time world player of the year scored on a penalty kick in the 53rd minute to put Brazil up 2-0, giving her 15 career World Cup goals and surpassing the 14 goals scored by Germany's Brigit Prinz.
Marta's penalty came after Formiga was fouled by South Korea's So-hyun Cho inside the box, and she sent the penalty into the lower left corner of the goal for the record score.
Formiga had Brazil's first goal, and the 37-year-old became the oldest player to score in tournament history - doing so in her sixth World Cup.
Brazil plays its second group-stage game against Spain on Saturday, while South Korea faces Costa Rica.
