Jill Ellis' United States side beat Netherlands 2-0 in the final to become the first American team to retain the trophy and, naturally, it was Rapinoe, the most prominent figure at the tournament, who was front and centre.
USA were held at bay for over an hour against a robust Dutch team. Goalkeeper Sari van Veenendaal was outstanding, brilliantly thwarting Julie Ertz, Sam Mewis and Alex Morgan - twice - in the first half.
But when Stefanie van der Gragt's studs caught Morgan's side, USA were awarded a penalty following a VAR review.
Rapinoe had the chance to alleviate the tension and put her country on course for that winning part US President Donald Trump placed as a feeble prerequisite for holding an opinion.
And so, in the 61st minute, Rapinoe stepped up and, with unnerving coolness, finally beat van Veenendaal.
