Kosmos 369 (Космос 369 meaning Cosmos 369), known before launch as DS-P1-Yu No.42, was a Soviet satellite which was launched in 1970 as part of the Dnepropetrovsk Sputnik programme. It was a 325 kg spacecraft, which was built by the Yuzhnoye Design Bureau, and was used as a radar calibration target for anti-ballistic missile tests.

The launch of Kosmos 369 took place from Site 133/1 at the Plesetsk Cosmodrome, and used a Kosmos-2I 63SM carrier rocket. The launch occurred at 15:10:03 UTC on 8 October 1970, and successfully deployed Kosmos 369 into low Earth orbit. Upon reaching orbit, it was assigned its Kosmos designation, and received the International Designator 1970-081A.

Orbit
Kosmos 369 was the thirty-sixth of seventy nine DS-P1-Yu satellites to be launched, and the thirty-third of seventy two to successfully reach orbit. It was operated in an orbit with a perigee of 256 km, an apogee of 454 km, 70.9 degrees of inclination, and an orbital period of 91.6 minutes. It remained in orbit until it decayed and reentered the atmosphere on 22 January 1971.
