Jamake Highwater, born as Jackie Marks, and also known as Jay or J Marks (14 February 1931–June 3, 2001), was an American writer and journalist of eastern European Jewish ancestry. From the late 1960s he claimed to be of Native American ancestry, specifically Cherokee. In that period, he published extensively under the name of Jamake Highwater. One version of his shifting story was that he had been adopted as a child and taken from his Indian home in Montana to grow up in a Greek or Armenian family in Los Angeles, California.
