Hermann Neubacher (June 24, 1893 – July 1, 1960) was an Austrian Nazi politician who held a number of diplomatic posts in the Third Reich. During the Second World War, he was appointed as the leading German foreign ministry official for the Balkans (including Greece, Serbia, Albania and Montenegro).
Born in Wels, he was educated in Kremsmünster and Vienna before seeing service in Italy in World War I. Initially connected to the Social Democratic Party of Austria through his friendship with a number of leading members whilst in charge of a housing project in Vienna, Neubacher became attracted to Pan-Germanism and in 1925 founded his own Österreichisch-Deutscher Volksbund as a society for this school of thought. He was also a member of the Deutsche Gemeinschaft secret society and in this group he built up friendships with fellow members Engelbert Dollfuß and Arthur Seyss-Inquart.
Neubacher became a member of the Nazi Party in Austria because he felt it was the best way to bring about Anschluss, although he was more in tune with the Anton Reinthaller-led moderate faction than the extremists under Theodor Habicht. After a spell as assistant to Josef Leopold he became Landesleiter of the Austrian Nazi party in 1935, attempting to restructure the banned group. His tenure came to an end the same year when he was imprisoned for distributing illegal material and upon his release he dropped out of politics to take up a role with IG Farben.
