Leo (Leopold) Junek (25 September 1899 – 13 July 1993) was a Croatian–French painter. He was a founding member of the Group Zemlja (Earth Group), one of the most influential movements in the history of Croatian art. He studied at the Zagreb Academy of Fine Arts, and subsequently moved to France, where he spent the rest of his life and was known as Lorris Junec. He is remembered for his sharp, geometric, colourful landscapes inspired by Post-Impressionism, Cubism, Fauvism, and Dada.
