The 27-year-old also won a fourth Ligue 1 title last season and claimed the French Cup and UEFA Super Cup, however PSG came up short in the final of the Club World Cup as Hakimi was forced to settle for a runners-up medal in New York.
The right-back beat out two past winners in Liverpool's Egyptian forward Mohamed Salah and Nigeria striker Victor Osimhen.
"It's really an honour for me to be here today and I'm proud to win such a prestigious trophy," Hakimi said, before thanking his family, teammates and Morocco coach Walid Regragui.
"This trophy, it's not just for me, it's for everybody in Africa and those that dream of becoming footballers."
Hakimi is currently nursing a severely sprained ankle but, if fit, will lead hosts Morocco in the Africa Cup of Nations from December 21 as they seek to win the competition again since 1976.
