Korcheva (Russian: Корчева) was a town in central Russia, on the territory of the modern Tver Oblast, on the Volga River, with a population of a few thousand people. It received town status in 1781 by the order of the empress Catherine II.
As the Ivankovo Reservoir and the Moscow Canal were constructed during the stalinist development of the Soviet Union, the town was abandoned and destroyed in 1936, and mostly submerged under the waters of the reservoir the next year. Most of the population was resettled into the nearby town of Konakovo. One can still find the only surviving house (which belonged to merchant Rozhdestvensky), a cemetery, and a foundation of the ruined Kazanskaya church at an impracticable bank of the reservoir.
