Dr. Hans Posse (6 February 1879 – 7 December 1942) was a German art historian, museum curator, and, for over three years, from June 1939 until his death, the special representative of Adolf Hitler appointed to expand the collection of paintings and other art objects which Hitler intended for the so-called "Führermuseum" in Linz, Austria. The museum, which was never built, was to be the core of a cultural center which was part of a planned general rebuilding of the city intended to have it surpass Vienna and rival Budapest.
