Megan Rapinoe and Team USA celebrated their World Cup victory with some MASSIVE bottles of champagne ... downin' bubbly and partying it up at the parade in NYC!!
Of course, it's the 4th World Cup victory for Team USA -- but this seems to be the biggest celebration yet ... the ratings for the women's World Cup in the U.S. were the biggest ever!
The champs pulled out all the stops for their big party -- with Rapinoe and her teammates passing around the huge gold bottle of Ace of Spades in the early hours of Wednesday's event.
The team took the stage following the parade and received keys to the city ... and Rapinoe -- who has publicly shared her issues with President Donald Trump -- shared a message of love for the crowd in attendance.
Team USA defeated the Netherlands 2-0 in the World Cup final. Rapinoe won the Golden Boot for scoring the most goals in the tourney ... and the girls have been celebrating the huge accomplishment ever since -- including a pool party with a bunch of dancing and rapping on Tuesday!!
The win had President Barack Obama pumped up for Team USA -- showing off his awesome custom jersey and saying, "Proud to rep America’s best team! Congrats @USWNT and thanks for being such a strong inspiration for women and girls—and everybody—all across the country."
