Ragnar Arthur Granit (30 October 1900 – 12 March 1991) was a Finnish and Swedish neurophysiologist who was awarded the Nobel Prize in Physiology or Medicine in 1967 along with Haldan Keffer Hartline and George Wald "for their discoveries concerning the primary physiological and chemical visual processes in the eye". Granit carried out fundamental research on the retina and the physiological mechanisms of colour vision at the University of Helsinki, and later investigated the neural control of movement at the Karolinska Institutet in Stockholm.
