Gregory D. S. Anderson is a linguist who is director of the Living Tongues Institute for Endangered Languages, a non-profit organization dedicated to the documentation, revitalization, and maintenance of endangered languages. In addition to endangered languages, Anderson is widely published and a recognized expert in historical linguistics, descriptive grammar, morphology, verb typology, and the linguistics of Munda, Turkic, Burushaski, Salishan, and Ogonoid languages.

Anderson has (co-) authored ten books and over 75 academic articles and edited several volumes on a wide array of topics. His recent books include Language Contact in South Central Siberia (2005), Auxiliary Verb Constructions (2006, paperback revised edition 2009), The Munda Verb: Typological Perspectives (2007) and The Munda Languages (2008).

Anderson is National Geographic Society fellow and heads the scientific research for the Enduring Voices Project. Anderson designed the scientific criteria for assessing language hotspots. The first version of the hotspots map was published in National Geographic magazine in October 2007 and has since become a leading metaphor for the global distribution of language extinction. A revised version of the language hotspots map is to be released in 2011.

Projects of Living Tongues are currently operating in India, Siberia, Papua New Guinea, the United States, and Paraguay.
