Sliman Mansour (Arabic: سليمان منصور‎, born in Birzeit, British Mandate of Palestine, 1947) is a Palestinian painter and writer, considered an important figure in Palestinian art. He has been described as an artist of the Intifada, whose work provides visual expressions of the Palestinian cultural concept of sumud (in English: constancy, steadfastness). He studied Fine Arts at the Bezalel Academy of Art and Design in Jerusalem from 1967 to 1970, and has been actively involved in Palestinian artistic life since that time. Like other Palestinian painters residing in the occupied territories, he has participated in several group exhibitions with Israeli artists. After the outbreak of the First Intifada, he was arrested and several of his works were confiscated for using the colors of the Palestinian flag (green, black, and red) in his paintings, which was illegal under Israeli law.
