Ferdinand André Fouqué (June 21, 1828 - March 7, 1904) was a French geologist and petrologist.
He was born at Mortain, in the Manche départment.
At the age of twenty-one he entered the École Normale in Paris, and from 1853 to 1858 he held the appointment of keeper of the scientific collections. In 1877 he became professor of natural history at the Collège de France, in Paris, and in 1881 he was elected a member of the Academy of Sciences.
As a stratigraphical geologist he rendered much assistance on the Geological Survey of France, but in the course of time he gave his special attention to the study of volcanic phenomena and earthquakes, to minerals and rocks; and he was the first to introduce modern petrographical methods into France.
His studies of the eruptive rocks of Corsica, Santorini and elsewhere; his researches on the artificial reproduction of eruptive rocks, and his treatise on the optical characters of feldspars deserve special mention; but he was perhaps best known for the joint work which he carried on with his friend Auguste Michel-Lévy.
His chief publications were: Santorin et ses eruptions, 1879; (with Michel-Lévy) Minéralogie micrographique, Roches éruptives françaises (2 vols., 1879); and Synthèse des minéraux et des roches (1885).
