Wilhelm Rietze (10 October 1903 – 28 August 1944) was a German communist and resistance fighter against Nazism.
He was a member of the Communist Party of Germany (KPD) from 1930, and also active in the workers' sports club "Nordwest".
On 29 January 1934 he was arrested by the Gestapo and interned in Columbia concentration camp; Rietze was sentenced to three years' imprisonment on 1 November 1934, which he served in Luckau prison.
