Fritz Wächtler (7 January 1891 – 19 April 1945) was a Nazi German politician and 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 Reich Defense Commissar of Bayreuth.
Prone to alcoholic outbursts and unpopular with the local residents, he eventually ran afoul of Martin Bormann in a political intrigue.
Wächtler was shot on the orders from Führer Headquarters near the end of the war on 19 April 1945.
