Leonid Ivanovich Rogozov (Russian: Леонид Иванович Рогозов, 14 March 1934 – 21 September 2000) was a Soviet general practitioner who took part in the sixth Soviet Antarctic Expedition in 1960–1961. He was the only doctor stationed at the Novolazarevskaya Station and, while there, developed appendicitis, which meant he had to perform an appendectomy on himself, a famous case of self-surgery.
