Johan Bernhard Hjort (25 February 1895 – 24 February 1969) was a Norwegian supreme court lawyer. Having joined the law firm of Harald Nørregaard in 1932, he continued the firm after World War II as Advokatfirmaet Hjort, which today is one of Norway's leading law firms. Hjort was also noted for his involvement with the fascist party, Nasjonal Samling, in the 1930s, but left the party in 1937 and became an active member of the anti-Nazi resistance during World War II. He was imprisoned by the Nazis and is credited with saving the lives of many prisoners through his involvement with the White Buses. After World War II, he rose to become one of Norway's preeminent lawyers, and was noted for his defence of gay rights and controversial artists, as chairman of the Riksmålsforbundet language society, and as a liberal public figure.
He was the son of marine biologist, oceanographer, and director of fisheries, Johan Hjort.
On 17 May (Norway's annual celebratory holiday) 1933, with Vidkun Quisling he founded the Nasjonal Samling, a political party based on Germany's Nazi Party. He and Quisling devised a programme of mostly very right-wing policies that included the outlawing of revolutionary parties (such as those funded by foreign bodies like Comintern), the suspension of the voting rights for people in receipt of social welfare, agricultural debt relief and an audit of public finances. Hjort became leader of the Hirden, the paramilitary wing of the Nasjonal Samling party that was modeled on the German Sturmabteilung, the Nazi "Brownshirts". In 1937 Hjort broke with Quisling and left Nasjonal Samling.
