Robert Abshagen (12 January 1911 in Hamburg – 10 July 1944) was a German Resistance fighter against National Socialism and a Communist.
In 1934, he was sentenced in Hamburg state supreme court of "Vorbereitung zum Hochverrat" (intent to commit treason) to two and a half years at hard labor in a Zuchthaus, which he spent in Bremen-Oslebshausen Prison in Gröpelingen.
Beginning in 1936, Bästlein and Volker Paddry recited poetry and prose they had learned by heart and Abshagen held programs on proletarian and progressive writings.
In this capacity, Abshagen traveled to Berlin, Saxony and Thuringia and made contact with anti-fascists in the Ruhr area.
The commission's findings related to the activities of Erna Eifler and Wilhelm Fellendorf swept up Abshagen on 19 October 1942.
