Carl Friedrich Georg Spitteler (24 April 1845 – 29 December 1924) was a Swiss poet who was awarded the Nobel Prize for Literature in 1919. His work includes both pessimistic and heroical poems.

Spitteler was born in Liestal, and from 1863 he studied law at the University of Zurich. In 1865 - 1870 he studied theology in the same institution, at Heidelberg and Basel. Later he worked in Russia as tutor, starting from August 1871, remaining there (with some periods in Finland) until 1879. Later he was elementary teacher in Bern and La Neuveville, as well as journalist for the Der Kunstwart and as editor for the Neue Zürcher Zeitung. In 1883 Spitteler married Marie op der Hoff, previously his pupil in Neuveville.

In 1881 Spitteler published the allegoric prose poem Prometheus and Epimetheus, published under the pseudonym Carl Felix Tandem, and showing contrasts between ideals and dogmas through the two mythological figures of the titles. This 1881 edition was given an extended psychological exegesis by Carl Gustav Jung in his book Psychological Types (published in 1921). Late in life, Spitteler reworked Prometheus and Epimetheus and published it under his true name, with the new title Prometheus der Dulder (Prometheus the Sufferer, 1924).

In 1900 - 1905 Spitteler wrote the powerful allegoric epic poem, in iambic hexameters, Olympischer Frühling (Olympic Spring). This work, mixing fantastic, naturalistic, religious and mythological themes, deals with human concern towards universe. His prose works include Die Mädchenfeinde (Two Little Misogynists, 1907), about his autobiographical childhood experiences, the dramatic Conrad der Leutnant (1898), in which he showed influence from the previously opposed Naturalism, and the autobiographical novella Imago (1906), examining the role of unconscious in the conflict between a creative mind and the middle class restrictions.

During World War I he opposed to the pro-German attitude of the Swiss German speaking majority, a position put forward in the essay "Unser Schweizer Standpunkt". In 1919 he won the Nobel Prize. Spitteler died at Lucerne in 1924.
