Walter Edmund Roth (2 April 1861 – 5 April 1933) was a British colonial administrator, anthropologist and medical practitioner, who worked in Queensland, Australia and British Guiana between 1898 and 1928.
Roth and his brother, Henry Ling Roth, are the subject of a joint biography by Russell McDougall & Iain Davidson: The Roth Family, Anthropology, and Colonial Administration (2008).[1]
