Werner Werenskiold (28 April 1883 – 2 August 1961) was a Norwegian geologist and geographer. He was a son of Erik Werenskiold and visual artist Sophie Marie Stoltenberg Thomesen (1849–1926), and the brother of Dagfin Werenskiold. Werenskiold made field studies in Telemark and Gudbrandsdalen in his younger days, and later focused on studies at Svalbard and of glaciers in Jotunheimen. He was the principal editor of the two-volume series Norge, vårt land (1936 – 1941) and the book series Jorden vår klode. He was a professor of geography at the University of Oslo from 1925.
