Hans Laternser (3 August 1908 in Diedenhofen – 21 July 1969 in Frankfurt am Main) was a German lawyer who specialised in Anglo-Saxon law.
He had represented several defendants at the Nuremberg Trials, such as former Field Marshals Albert Kesselring and Erich von Manstein.
He represented Wilhelm von Leeb, a former field marshal who had been in command of Army Group North during the invasion of the Soviet Union, Operation Barbarossa.
Laternser acted as the de facto lead defence counsel for the entire group of defendants, who were former high-ranking personnel in the Wehrmacht of Nazi Germany.
He claimed that Leeb knew nothing of the activities of the Einsatzgruppen, the mobile SS death squads that were tasked with the murder of Jews, communists and Soviet prisoners-of-war in his area of command.
