The Kosmos-1 (GRAU Index: 65S3,[1] also known as Cosmos-1) was a Soviet carrier rocket, derived from the R-14 missile, which was used to orbit satellites in 1964 and 1965. It served as an interim, and was quickly replaced by the Kosmos-3. Eight were flown, and all launches occurred from Site 41/15 at the Baikonur Cosmodrome.

Initial development was authorised in October 1961,[2] leading to a maiden flight on 18 August 1964, carrying three Strela satellites. Strela-1 satellites were flown on seven flights, with three satellites on each of the first four flights, and five satellites on the next three flights. The eighth, and final, flight carried a single Strela-2 satellite. All flights were successful except the second.[1][2]
