Henri Choussat (24 March 1906 in Montpellier, France - 18 November 1994) was a French gerontologist. Choussat's father, a medical doctor, moved his family to Lafayette, Algeria, where Choussat spent his early years. In 1920, he joined the School of Algiers, where he passed his baccalauréat at age 17. He began to study medicine and law, eventually focusing on medicine. In 1962, with the independence of Algeria, Choussat was assigned to the Faculty of Medicine of Bordeaux as professor of Symptomatology, and later Medical Pathology. He focused on Gerontology until his retirement in 1977.
