Hippolyte Morestin (1 September 1869 – 12 February 1919) was a French surgeon, and associate professor of anatomy at the University of Paris.
He was dubbed "The Father of the Mouths" after his breakthroughs in oral and maxillofacial surgery.
Morestin was born at Basse-Pointe, a commune in the French overseas department of Martinique.
Morestin greatly influenced the British-New Zealand surgeon Harold Gillies, who met him on leave in Paris during the First World War.
Morestin, when Gillies was observing him, removed a tumor from a patient's face, and essentially "grafted" skin by cutting and rolling it from the patient's jaw onto the wound to allow the skin to regrow.
