Ernst Alfred Cassirer (/kɑːˈsɪərər, kəˈ-/ kah-SEER-ər, kə-; German: [ˈɛʁnst kaˈsiːʁɐ]; July 28, 1874 – April 13, 1945) was a German philosopher and historian of philosophy. Trained within the Neo-Kantian Marburg School, he initially followed his mentor Hermann Cohen in attempting to supply an idealistic philosophy of science.

After Cohen's death in 1918, Cassirer developed a theory of symbolism and used it to expand the "logic and psychology of thought" into a more general "logic of the cultural sciences". Cassirer was one of the leading 20th-century advocates of philosophical idealism. His most famous work is the Philosophy of Symbolic Forms (1923–1929).

Though his work received a mixed reception shortly after his death, more recent scholarship has remarked upon Cassirer's role as a strident defender of the moral idealism of the Enlightenment era and the cause of liberal democracy at a time when the rise of fascism had made such advocacy unfashionable. Within the international Jewish community, Cassirer's work has additionally been seen as part of a long tradition of thought on ethical philosophy.
