Emil Grünzweig (Hebrew: אמיל גרינצווייג) (December 1, 1947 – February 10, 1983) was an Israeli teacher and peace activist affiliated with the Peace Now movement. He became an icon of the Israeli left after he was killed by a grenade thrown at a peace rally in Jerusalem in 1983. In 1987, a nonprofit educational organization in Jerusalem was established in his name, called the Adam Institute for Democracy and Peace in Memory of Emil Greenzweig.
