Magda Langhans (born Magda Kelm: 16 July 1903 - 17 January 1987) was a Hamburg political activist and politician (KPD). Because of her political beliefs and activities she spent six of the twelve Nazi years in jail. After the war she resumed her membership of the Hamburgische Bürgerschaft (Hamburg state legislature). There is a street named after Magda Langhans in Potsdam, but not in her own city, Hamburg.
