Constantin Mimi (10 March 1868 – 17 April 1935) was a Bessarabian politician and winemaker, whose family had noble origins.

2 July] 1917, Constantin Mimi, the official Commissar of the Russian Provisional Government (of Kerenski) in Chişinău, gathered delegates of all major political, national, professional and administrative organizations to a "delegation" to protest and reject the pretensions of the Ukrainian Central Rada to annex Bessarabia.

The Peasants Congress, which took place in October 1917, voted Constantin Mimi out and Ion Inculeţ as the new Commissar.

This move was planned by Alexander Kerenski, who sent Inculeţ, an associate professor at the University of Petrograd, to Bessarabia to take hold of the situation.

As soon as the Peasants Congress, which had no legal power, voted, Kerenski formally replaced Mimi with Inculeţ.
