A Sacred Duty: Applying Jewish Values to Help Heal the World is a 2007 American documentary film written, directed, and produced by Lionel Friedberg. It was distributed by Jewish Veg, then known as the Jewish Vegetarians of North America (JVNA). The film centers on Jewish teachings about caring for the planet, treatment of animals, and the environment, with a focus on Jewish vegetarianism. Interviews with rabbis, activists, and scholars are interspersed with footage and stills illustrating the points being discussed.

Jewish vegetarianism is a commitment to vegetarianism that is connected to Judaism, Jewish ethics or Jewish identity. Jewish vegetarians often cite Jewish principles regarding animal welfare, environmental ethics, moral character, and health as reasons for adopting a vegetarian or vegan diet.
