Michael Achmeteli (Georgian: მიხეილ ახმეტელი, Mikheil Akhmeteli) (1895–1963) was a Georgian émigré scholar, an expert on Soviet agriculture and sometime chief of Wannsee Institut, the SS-controlled research institute of Soviet studies in Nazi Germany.
Achmeteli obtained a doctorate at Jena in 1925 and joined the Institute of Eastern Europe in Breslau (now Wrocław, Poland) in 1926.
He was initially on friendly terms with Alfred Rosenberg and the authorities expected him to provide the expertise on Soviet economy.
Under the pseudonym Konstantin Michael, he wrote a book on Soviet agriculture and forced collectivization.
After the war, Achmeteli settled in Munich and worked as professor at the Ludwig Maximilian University.
