Romain Langasque (born 18 May 1995) is a French professional golfer who plays on the European Tour. He won The Amateur Championship in 2015 and in 2020 had his biggest professional success when he won the ISPS Handa Wales Open.
Langasque won The Amateur Championship in 2015 at Carnoustie Golf Links, beating Grant Forrest 4 and 2 in the final.
His Amateur Championship win gave an entry to the 2015 Open Championship where he made the cut and finished tied for 65th place. He also got an entry to the 2016 Masters Tournament where he was one of two amateurs to make the cut and finished tied for 39th place.
Langasque turned professional after the 2016 Masters Tournament, thus forfeiting his exemption into the 2016 U.S. Open.
