Martin Weise (12 May 1903 – 15 November 1943) was a German journalist, member of the Communist Party of Germany (KPD) and a resistance fighter against the Nazis during World War II.

[1] He learned that his fiancée Baroness Frieda Seidlitz [de], who had worked as a courier for the KPD, had committed suicide in prison on 27 May 1936, after succumbing to Gestapo abuse while in custody.

After his release from the concentration camp in April 1939, Weise re-established contact with his friends, including Wilhelm Guddorf.

[3] Together with John Sieg, Fritz Lange and Walter Husemann, Weise regularly distributed the underground journal Die Innere Front (The Home Front) in Berlin from the end of 1941, which contained appeals, information about the general situation and references to the broadcast frequencies of Moscow radio.

On 8 October 1943 the 2nd Senate of the People's Court condemned him to death because of "preparation for high treason and because of enemy favouritism".
