Kosmos 37 (Russian: Космос 37 meaning Cosmos 37) or Zenit-2 No.22 was a Soviet optical film-return reconnaissance satellite launched in 1964. A Zenit-2 spacecraft, Kosmos 37 was the twentieth of eighty-one such satellites to be launched and had a mass of 4,730.0 kilograms (10,427.9 lb).
Kosmos 37 was launched by a Vostok-2 rocket, serial number R15001-04, flying from Site 31/6 at the Baikonur Cosmodrome. The launch took place at 09:36 UTC on 14 August 1964, and following its successful arrival in orbit the spacecraft received its Kosmos designation; along with the International Designator 1964-044A and the Satellite Catalog Number 848.
Kosmos 37 was operated in a low Earth orbit; at an epoch of 19 August 1964 it had a perigee of 203 kilometres (126 mi), an apogee of 285 kilometres (177 mi) inclination of 64.9 degrees and an orbital period of 89.38 minutes. During the mission one of the satellite's film reels snapped, resulting in the associated camera only taking some of the images it had been programmed to produce. On 22 August 1964, after eight days in orbit, Kosmos 37 was deorbited with its return capsule descending by parachute for recovery.
