Kosmos 76 (Russian: Космос 76 meaning Cosmos 76), also known as DS-P1-Yu No.3 was a Soviet satellite which was used as a radar calibration target for tests of anti-ballistic missiles. It was built by the Yuzhnoye Design Bureau, and launched in 1965 as part of the Dnepropetrovsk Sputnik programme.
Kosmos 76 was launched using a Kosmos-2I 63S1 carrier rocket, which flew from Site 86/1 at Kapustin Yar. The launch occurred at 04:33 UTC on 23 July 1965.
Kosmos 76 separated from its carrier rocket into a low Earth orbit with a perigee of 255 kilometres (158 mi), an apogee of 499 kilometres (310 mi), 48.7 degrees of inclination, and an orbital period of 92.09 minutes. It decayed from orbit on 16 March 1966. Kosmos 76 was the third of seventy nine DS-P1-Yu satellites to be launched, of which all but seven were successful. It replaced the previous satellite, DS-P1-Yu No.2, which had failed to reach orbit due to a second stage malfunction
