The Ethical movement is an ethical, educational, and religious movement established in 1877 by the academic Felix Adler (1851–1933). In an effort to develop humanist codes of behavior, the Ethical movement emerged from the moral traditions of the secular societies of Europe and the secular society of the 19th-century United States. In practice, the Ethical movement organized themselves as two types of organization: (i) a secular humanist movement and (ii) a predominantly moral movement with a religious approach.

Felix Adler was a German American professor of political and social ethics, rationalist, influential lecturer on euthanasia, religious leader and social reformer who founded the Ethical Culture movement.
