Yohanan Simon was a German-born Israeli painter.

He was a member of Kibbutz Gan Shmuel.

He was known and admired as one of Israel’s ideological Realist painters, who were fully committed to the socialist collective idea. Yohanan Simon was active in the Haganah and participated in the War of Liberation. In 1953 he left the kibbutz, moved to Tel Aviv and opened a studio. Yohanan Simon's early work can be described as Social Realist as he used to paint Kibbutz scenes. In his mature work, after he traveled in South America, he freed himself from the social realism and became more abstract and colorful. His work was influenced by the Fauvism of Fernand Leger, André Derain and Diego Rivera.
