Louis Édouard Gourdan de Fromentel (29 August 1824, Champlitte – 6 April 1901, Bouhans-et-Feurg) was a French physician and paleontologist known for his study of fossil coral polyps and sponges.

He studied medicine at the University of Strasbourg, then relocated to Paris, where he served as an intern at Val-de-Grâce. In 1849 he obtained his medical doctorate, and during the following year, settled in the town of Gray (Haute-Saône). As a physician he dealt with epidemics such as typhoid and worked as a prison doctor. For a period of time he served as vice-president of the Conseil d'hygiène.
