(Old Norse nominative Gautr; variants Gauti, Gaute, Guti, Gapt; latinized Gothus; Old English Geat) is an early Germanic name, from a Proto-Germanic gautaz, which represents an eponymous founder or tribal god of a number of related Germanic tribes of the migration period, i.e. the Gautar (*, Geats), Gutans (*, Goths) and Gutes (Gotlanders). Gautr is also one of the Eddaic names of Odin.

Marie Clément Gaston Gautier (10 April 1841 – 7 October 1911) was a French botanist and agriculturalist.
