Megan Rapinoe has been awarded Sports Illustrated's Sportsperson of the Year for 2019.

The American, who won the World Cup with the USA in July, was also awarded the golden boot and golden ball at the tournament.

Off the field, she has been extremely vocal on the matter of gender equality as well as having a very public Twitter spat with US President Donald Trump.

And co-editor-in-chief of Sports Illustrated, Steve Canella, described Rapinoe as a trailblazer.

"Even in a year with many great candidates, choosing Megan as the Sportsperson of the Year was an easy decision," he said.

"She is a force of nature on and off the field, a trailblazing soccer player who also proves every day how large and loud a voice a socially conscious athlete can have in 2019."

Meanwhile, US teammate Alex Morgan took to Twitter to praise Rapinoe for her stellar year.

"So happy to see @MPinoe win @SInow #Sportsperson of the Year," said Morgan.

"You stand for something bigger and I stand with you. #VWAmbassador #DriveBigger @vw."
