Émile Souvestre (April 15, 1806 – July 5, 1854) was a Breton novelist who was a native of Morlaix, Brittany. Initially unsuccessful as a writer of drama, he fared better as a novelist (he wrote a sci-fi novel, Le Monde Tel Qu'il Sera) and as a researcher and writer of Breton folklore. He was posthumously awarded the Prix Lambert.
