Anton Josef Trčka (7 September 1893 – 16 March 1940) was an Austrian-born Czech photographer, painter and poet. He was mostly known for his portraits, which he signed with the name "Antios," a combination of his first and middle names. His studio was destroyed by a bomb in 1944, and photographs of artists Gustav Klimt and Egon Schiele are some of the few surviving examples of his work. Trčka died from carbon monoxide poisoning aged 46. He was married to Clara Schlesinger.
