Kosmos 211 (Russian: Космос 211 meaning Cosmos 211), also known as DS-P1-Yu No.13 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 1968 as part of the Dnepropetrovsk Sputnik programme.^[3] It had a mass of 400 kilograms (880 lb).^[1]

A Kosmos-2I 63SM carrier rocket was used to launch Kosmos 211 from Site 133/3 at Plesetsk Cosmodrome.^[4] The launch occurred at 11:26:25 GMT on 9 April 1968, and resulted in the successful deployment of Kosmos 211 into a low Earth orbit.^[5] Upon reaching orbit, it was assigned its Kosmos designation, and received the International Designator 1968-028A.

Kosmos 211 was operated in an orbit with a perigee of 199 kilometres (124 mi), an apogee of 1,532 kilometres (952 mi), an inclination of 81.9°, and an orbital period of 102.5 minutes.^[2] It remained in orbit until it decayed and reentered the atmosphere on 10 November 1968.^[6] It was the twelfth of seventy nine DS-P1-Yu satellites to be launched, and the eleventh of seventy two to successfully reach orbit.^[7]
