Émile Argand (January 6, 1879 – September 14, 1940) was a Swissgeologist.
He was born in Eaux-Vives near Geneva. He attended vocational school in Geneva then worked as a draftsman. He studied anatomy in Paris, but gave up medicine to pursue his interest in geology.
He was an early proponent of Alfred Wegener's theory of continental drift, viewing plate tectonics and continental collisions as the best explanation for the formation of the Alps. He is also noted for his application of the theory of tectonics to the continent of Asia.
