After the success of the 2023 edition in Australia and New Zealand, which earned a record $570 million in commercial revenue, FIFA chose to continue its push to expand women's football by taking the tournament to South America for the first time.
Delegates meeting in Bangkok voted by 119 votes to 78 to send the 10th edition to the land of samba football, sparking jubilant celebrations from the Brazilian bid team.
Brazil, home of women's football great Marta, scored higher than its European rival in FIFA's evaluation report.
The FIFA inspectors noted the "tremendous impact on women's football in the region" that South America hosting the Women's World Cup would have.
Brazil's bid includes 10 stadiums used for the men's World Cup in 2014, with Rio de Janeiro's famous Maracana lined up for the opening match and the final.
But work needs to be done, in particular to the Amazonia stadium in Manaus which has stood almost unused for a decade.
The Brazilian Football Confederation (CBF) has also been in turmoil with legal challenges to its president.
Unlike their male counterparts, who have won five World Cups, Brazil's women have never lifted the trophy and made a group-stage exit in 2023.
The 2023 tournament defied fears that increasing the size fro 24 to 32 teams would dilute the spectacle, with over 1.4 million fans streaming through the turnstiles to witness a host of shocks, dramatic turnarounds and breakthrough results.
Gone were the lopsided scorelines that were a feature of the previous eight World Cups, reflecting a growth in the standard of women's football.
Seven teams notched their first World Cup wins and the United States and Germany, who between them had won six of the previous eight tournaments, were both dumped out early.
The only sour note came in the aftermath of last year's final in Sydney, in which Spain beat England 1-0.
Spanish football federation (RFEF) chief Luis Rubiales sparked outrage when he forcibly kissed midfielder Jenni Hermoso during the medal ceremony, and now faces prosecution for sexual assault.
Gaza debate
The 74th FIFA congress, making its debut in Premier League-mad Thailand, made its choice by open vote for the first time as the organisation seeks to move on from the corruption and shady dealing that dogged it in the past.
Delegates had their choice simplified last month when the United States and Mexico withdrew their joint bid, deciding instead to focus on trying to win the right to stage the 2031 edition.
As the Brazil tournament approaches, the focus will be on the huge financial disparity between men's and women's football.
Prize money for the 2023 Women's World Cup was a record $110 million, but still far short of the $440 million on offer to teams at the 2022 men's finals in Qatar.
The congress also heard a call from the Palestinian FA (PFA) to suspend Israel from the world body and ban Israeli teams from FIFA events.
PFA head Jibril Rajoub said the Israeli FA (IFA) had broken FIFA rules, adding: "FIFA cannot afford to remain indifferent to these violations or to the ongoing genocide in Palestine."
His Israeli counterpart Shino Moshe Zuares rejected the call as "cynical, political and hostile", insisting the IFA had not broken any FIFA rules.
FIFA supremo Gianni Infantino said the body would take independent legal advice on the matter and decide by July 20 what action to take, if any.
Statute changes
The congress also approved changes to FIFA statutes, removing the rule fixing the organisation's headquarters in Zurich, where it has been since 1932.
The rule now says the location of the HQ will be "determined by a decision passed by the congress" -- opening the way for it to move from the Swiss city.
Delegates also voted to multiply the number of committees from seven to 35, reversing steps taken in 2016 to clean up FIFA after it was rocked by a wave of corruption scandals.
The remits of the new committees include women's football, the fight against racism and eSports, but critics say they risk re-establishing a patronage system the reforms had sought to abolish.
