Elly Winter (née Pieck; 1 November 1898 – 13 May 1987)[1] was a German communist and notable political activist.

The eldest daughter of East German president Wilhelm Pieck, Elly Winter was a longtime activist in the anti-fascist movement and was a well-recognized member of the Socialist Unity Party (SED) in East Germany after the Allied triumph over Nazism.

Theodor Winter, who fought the Nazis in armed struggle, was arrested by the Gestapo and executed during the Second World War.

The Socialist Unity Party elected Wilhelm Pieck to assume the function of president in newly formed German Democratic Republic (East Germany) in 1949, and Winter continued to act as an assistant and personal secretary to her father, caring for him in his last period of illness just prior to his death in 1960.

Concurrently, Winter was a leading member of the Institute for Marxism-Leninism of the Central Committee of the Socialist Unity Party of Germany in East Berlin, where she died in 1987.
