Hans Knirsch (14 September 1877 in Třebařov – 6 December 1933 in Duchcov) was an Austro-German activist from Moravia for Austrian Nazism.

Together with Rudolf Jung and Hans Krebs, he was one of the original core that remained in the Nazi Party after 1933.

In that capacity he published an appeal which extolled the political unification of all Germans into one state, referring to it as der alte Sehnsuchstraum der deutschen Demokraten ("the old nostalgic dream of the German democrats").

Active in several party congresses, before World War I he attempted to get the DAP to add the words "National Socialist" to their name.

It was Hans Knirsch who talked Hitler out of his depression and convinced him to resume eating.
