Herbert Czaja (November 5, 1914 – April 18, 1997) was a German Christian democratic politician. Czaja was born to a multi-ethnic and multilingual family in Cieszyn in Poland, which was part of Austria-Hungary at the time of his birth. During the Second Polish Republic he was politically active in the German Christian People's Party, a centrist party representing German-speaking Catholics in Poland, and obtained a doctorate in philology from the Jagiellonian University. In 1946 he was expelled from his native Poland by the communist regime during the expulsion of Germans after World War II and came as a refugee to Stuttgart in West Germany, where he worked as a teacher and became active in politics for the Christian Democratic Union.
