Johann Nikuradze (November 20, 1894 - July 18, 1979) was a Georgia-born German engineer and physicist. His brother, Alexander Nikuradze, was also a Germany-based physicist and geopolitician known for his ties with Alfred Rosenberg and for his role in saving many Georgians during World War II. He was born in Samtredia, Georgia (then part of the Kutais Governorate, Imperial Russia) and studied at Kutaisi. In 1919, through the recommendations of the prominent Georgian scholar Petre Melikishvili, he went abroad for further studies. The 1921 Sovietization of Georgia precluded his return to his homeland, and Nikuradze naturalized as a German citizen.
