Arthur March (23 February 1891 – 17 April 1957) was an Austrian physicist.

From 1909 he studied mathematics and physics at the Universities of Innsbruck, Munich and Vienna, earning his doctorate in 1913. In 1917 he obtained his habilitation, and in 1928 became an associate professor at Innsbruck. From 1934 to 1936 he was a visiting professor at the University of Oxford, afterwards returning to Innsbruck as a full professor of theoretical physics.

March is known for his research in the field of quantum mechanics. One of his more intriguing projects involved finding the smallest space-time distance.^[1][2]
