The Oregon Direct Legislation League was an organization of political activists founded by William S. U'Ren in the U.S. state of Oregon in 1898. U'Ren had been politically activated by reading the influential 1893 book Direct Legislation Through the Initiative and Referendum, and the group's founding followed in the wake of the 1896 founding of the National Direct Legislation League, which itself had its roots in the Direct Legislation League of New Jersey and its short-lived predecessor, the People's Power League.
