Josiah Warren (; 1798 – April 14, 1874) was an individualist anarchist, inventor, musician, and author in the United States. He is widely regarded as the first American anarchist, and the four-page weekly paper he edited during 1833, The Peaceful Revolutionist, was the first anarchist periodical published, an enterprise for which he built his own printing press, cast his own type, and made his own printing plates.
