Viktor Dyk (December 31, 1877, Pšovka u Mělníka, Austria-Hungary – May 14, 1931, near the island of Lopud, Yugoslavia) was a well-known Czech poet, prose writer, playwright, politician and political writer.
His writings were politically charged and designed to inspire nationalism in the fight to reclaim the Czech Republic from Austrian rule.
Viktor Dyk studied at a gymnasium in Prague (one of his teachers was Alois Jirásek) and then at the Faculty of Law of Charles University in Prague.
In 1911, he became involved in politics and joined the Státoprávně pokroková strana. During the First World War, he was imprisoned in Vienna for his resistance activities against Austria-Hungary. In 1918, he co-founded the Czechoslovak National Democratic Party (in Czech: Československá národní demokracie).
His political views were conservative and nationalist. In the times of the First Republic of Czechoslovakia, Viktor Dyk was one of the prominent intellectual opponents of President Tomáš Garrigue Masaryk.
Viktor Dyk died of a heart failure while swimming in the sea near the island of Lopud.
