Trygve Lange-Nielsen (9 July 1921 – 18 April 2014) was a Norwegian barrister and judge. He was born in Kristiania as a son of Fredrik Lange-Nielsen (1891–1980) and Laura Stang Lund (1893–1961). He was a maternal grandson of Fredrik Stang Lund. In 1953 he married Sissel Herlofson. His special fields included insurance law—he chaired Norsk forsikringsjuridisk avdeling from 1971 to 1982—and tort law, in which he lectured at the University of Oslo. He did however become better known for unveiling and overturning miscarriage of justice cases, an endeavor to which he dedicated his later life.
