Corentin Rahier (born 30 August 1998) is a French former competitive ice dancer.
With his skating partner, Natacha Lagouge, he is the 2017 JGP Cup of Austria bronze medalist and 2017 French national junior champion.
Lagouge/Rahier received two ISU Junior Grand Prix assignments; they placed 6th in Saint-Gervais-les-Bains, France, and 4th in Ljubljana, Slovenia.
In September 2017, Lagouge/Rahier won the bronze medal at the ISU Junior Grand Prix in Austria.
They withdrew from JGP Croatia; Lagouge fractured her hand during a practice before the short dance, competed for the first segment and finally gave up and returned to Lyon for an operation.
