Archibald Stansfeld Belaney September 18, 1888 – April 13, 1938), commonly known as Grey Owl, was a British-born conservationist, fur trapper, and writer who disguised himself as a Native American man. While he achieved fame as a conservationist during his life, after his death, the revelation that he was not Indigenous, along with other autobiographical fabrications, negatively affected his reputation.
