And her decision to not sing the American national anthem as a self-proclaimed "walking protest" against Donald Trump's policies has drawn criticism from the US president himself.
The reigning champion US team has been on a tear so far in the FIFA Women's World Cup.
Rapinoe - one of three co-captains of the side - scored two penalties as the U.S. beat Spain 2-1 in the last-16 of the competition in Reims on Monday, and they'll now face hosts France in the quarter-finals in Paris on Friday.
Rapinoe, 33, followed the lead of former San Francisco 49ers quarterback Kaepernick in 2016 by kneeling during the anthem.
Asked if he thought U.S. co-captain Rapinoe's actions were appropriate, Trump told The Hill: "No".
"I'll probably never put my hand over my heart", Rapinoe defiantly crowed as the women's team prepped for their World Cup run. "I mean who draws more, where is the money coming in".
She is one of the faces of the US team, and she has been willing to use her platform to make a stand beyond soccer.
"I love watching women's soccer", he said, according to The Hill.More news: Pompeo-Modi talks have 2 problems - Iran and trade

In March, 28 members of the U.S. women's team filed a gender discrimination lawsuit against US Soccer, citing gaps in pay and resources.
Trump also canceled a visit from the 2018 Super Bowl champions Philadelphia Eagles because of controversy over standing for the national anthem at games.
In the 2 1/2 years since Trump took office, many athletes have made it known they're displeased with his administration - perhaps none more clearly than Rapinoe.
Contrary to how the media are going to portray it, the president did so by succinctly stating his opposition and praising the entire women's soccer team. I know that when you have the great stars like [Portugal's Cristiano] Ronaldo and some of these stars. that get paid a lot of money, but they draw hundreds of thousands of people.
She added that the fact that she, an openly gay athlete, wears a USA jersey is "kind of a good "F you" to any sort of inequality or bad sentiments that the administration might have towards people who don't look exactly like [Trump]".
But Trump told The Hill he was still enjoying the U.S. Women's National Team's World Cup performance. "And I will do whatever it takes to be part of the solution".
