Georges Oltramare (born 17 April 1896 in Geneva – died 16 August 1960 in Geneva) was a Swiss author and fascist politician who became involved in collaboration in Nazi-occupied France.
Born into a leading Geneva family, he obtained a demi-licence in law at the University of Geneva in 1919.
He became a noted author, winning the Foundation Schiller prize for his 1927 novel Don Juan ou la Solitude and also wrote for a number of right wing journals, specifically Le Pilori, which specialized in anti-Semitism.
This fascist movement, which represented the country's French population, gained little support, although Oltramare was invited to participate in the anti-communist Entente nationale genevoise with more conservative parties in 1936.
Arrested for compromising Switzerland's independence, he spent the next few years in and out detention before being freed in 1952.
He went on to live in Spain and Egypt, where he briefly worked as a propagandist for the regime of Gamal Abdel Nasser, before returning to Switzerland where he was allowed to revive Le Pilori, which this time combined Poujadism with anti-Semitism.
Notwithstanding a sentence of death that had been passed on him by a French court in 1950 Oltramare died of natural causes in Geneva.
