Johanne Defay (born 19 November 1993) is a French professional surfer.
She began surfing at the age of 8 off the beaches of Reunion Island, which is her home today.
After Johanne's first competition when she was only ten years old, she quickly moved through the European amateur ranks to eventually take on the WSL World Qualifying Series.
She was finding it difficult to transition from the juniors to the WQS and then the economy crashed causing many surf companies cancel their sponsorships.
However, with her parents’ encouragement, Johanne was able to qualify for the World Championship Tour within two years.
