Ludwig von Sarnthein (4 January 1861, in Hermannstadt – 1 February 1914, in Hall, Tyrol) was a government administrator and botanist from the Austro-Hungarian Empire.
He obtained his education in Innsbruck, later serving as a government official in Brixen and Trieste (from 1892), Innsbruck (1905) and Ampezzo (1906), where he ultimately attained the rank of Bezirkshauptmann (district governor).
[1][2] With Karl Wilhelm von Dalla Torre, he was co-author of works associated with the flora of Tyrol, Vorarlberg and Liechtenstein.
As taxonomists, the two men co-described numerous botanical species.
