Aurier, 22, joined PSG on a season-long loan from fellow Ligue 1 outfit Toulouse and has impressed manager Laurient Blanc on the right-back position.
The full-back has now signed a four year contract which will see him remain at the Parc des Princes until 2019.
The Ivory Coast international said: “I am enjoying magnificent season, both on an individual and team level. I am very proud that the Club is again showing its confidence in me. I will continue to progress to help the team reach the summits of the game, both in France and Europe.”
He tore his hamstring in the 2-2 draw with Caen in February, a week after his triumph with the Elephants at this year’s Africa Cup of Nations (Afcon) in Equatorial Guinea, but has managed 12 league appearances for the side despite the setback.
