Kosmos 165 (Russian: Космос 165 meaning Cosmos 165), also known as DS-P1-Yu No.11 was a radar calibration target satellite which was used by the Soviet Union for tests of anti-ballistic missiles. It was a 400 kilograms (880 lb) spacecraft, which was built by the Yuzhnoye Design Office, and launched in 1967 as part of the Dnepropetrovsk Sputnik programme.
Kosmos 165 separated from its carrier rocket into a low Earth orbit with a perigee of 198 kilometres (123 mi), an apogee of 1,515 kilometres (941 mi), an inclination of 81.9°, and an orbital period of 102.1 minutes. It decayed from orbit on 15 January 1968. Kosmos 165 was the eighth of seventy nine DS-P1-Yu satellites to be launched, and the seventh of seventy two to successfully reach orbit.
