Fritz Wächtler (7 January 1891 – 19 April 1945) was a Nazi Party official and politician who served as the Gauleiter of the eastern Bavarian administrative region of Gau Bayreuth. Trained as a primary school teacher, he also became head of the National Socialist Teachers League (NSLB) in 1935. During World War II he held the honorary rank of SS-Obergruppenführer and was the Reich Defense Commissioner of Gau Bayreuth. Prone to alcoholic outbursts and unpopular with the local residents, he eventually ran afoul of Martin Bormann in a political intrigue. Wächtler was executed on orders from Führer Headquarters near the end of the war on 19 April 1945.
