Vilko Gecan (16 June 1894 – 25 June 1973) was a Croatian painter, influential in the Zagreb modern art scene of the 1920s and 1930s. He is best known for his expressionist paintings and drawings, and for his contributions to the local avantgarde magazine Zenit. He showed his work in many solo and group exhibitions in Croatia and abroad. In the Zagreb Spring Salon of the 1920s, he participated with Milivoj Uzelac, Marijan Trepše and Vladimir Varlaj, who together were known as the "Group of Four" or "The Prague Four". Trained in Prague, works of these young painters brought new expressionist ideas that went on to dominate the 1920s Croatian art scene.
