Hans von Hayek (19 December 1869, in Vienna – 17 January 1940, in Munich) was an Austrian-born German Impressionist painter. He was born on 19 December 1869 in Vienna to Theodor von Hayek and Marie Cäcilie Wittek. His paternal uncle was the naturalist Gustav von Hayek, and his first cousin was Gustav's son, August von Hayek, who was the father of economist Friedrich Hayek.

In 1891, after a short period of study at the University of Applied Arts in Vienna, he moved to Munich and enrolled at the Academy of Fine Arts, where he studied with Gabriel von Hackl, Wilhelm von Lindenschmit and Carl von Marr. Later, he met the animal painter, Heinrich von Zügel, who ultimately had the most influence on his style.
