Dimitri Navachine (Дмитрий Сергеевич Навашин; 30 August 1889 – 25 January 1937) was a Russian politician and economist. He governed the BCEN-Eurobank in France from 1927 to 1929. In addition, he served as a consultant to the French Popular Front to offer advice on combating the economic crisis in France. Ideologically, Navachine was a socialist but his politics and theories were more closely associated with the Popular Front, not Marxism–Leninism. Although well-respected for his economic views in France, Navachine nonetheless created many enemies both there and in the Soviet Union. He was assassinated in 1937 but his case still remains unsolved.
