The Shvetsov ASh-62 (designated M-62 before 1941) is a nine-cylinder, air-cooled, radial aircraft engine produced in the Soviet Union. It was a development of the Wright Cyclone that had been built there under licence as the M-25, the main improvements including a two-stage supercharger and a more efficient induction system. Power was increased from the Cyclone's 775 hp to 1,000 hp. First run in 1937, licenced versions are still in production by WSK "PZL-Kalisz" in Poland as the ASz-62 (as of 2007). The Ash-62 was also produced in China. It is estimated that 40,361 were produced in the USSR.

Polish-built ASz-62IR are compatible with FAR-33 requirements. Further development in Poland are K9-AA, K9-BA and K9-BB engines, with take-off power 1178 hp (860 kW), indicated power 698 kW. The K9-BA engine might be fitted to DC-3 Dakota.
