The R-14 Chusovaya was a single stage Intermediate-range ballistic missile developed by the Soviet Union during the Cold War. It was given the NATO reporting name SS-5 Skean and was known by GRAU index 8K65. It was designed by Mikhail Yangel. Chusovaya is the name of a river in Russia. Line production was undertaken by Facility No. 1001 in Krasnoyarsk.

An intermediate-range ballistic missile (IRBM) is a ballistic missile with a range of 3,000–5,500 km, between a medium-range ballistic missile (MRBM) and an intercontinental ballistic missile (ICBM). Classifying ballistic missiles by range is done mostly for convenience. In principle there is very little difference between a low-performance ICBM and a high-performance IRBM, because decreasing payload mass can increase the range over the ICBM threshold. The range definition used here is used within the U.S. Missile Defense Agency.
