The Buk missile system (Russian: "Бук"; “beech” (tree), /bʊk/) is a family of self-propelled, medium-range surface-to-air missile systems developed by the Soviet Union and its successor state, the Russian Federation, and designed to fight cruise missiles, smart bombs, fixed- and rotary-wing aircraft, and unmanned aerial vehicles.

The Buk missile system is the successor to the NIIP/Vympel 2K12 Kub (NATO reporting name SA-6 "Gainful"). The first version of Buk adopted into service carried the GRAU designation 9K37 and was identified in the west with the NATO reporting name "Gadfly" as well as the US Department of Defense designation SA-11.

With the integration of a new missile the Buk-M1-2 and Buk-M2 systems also received a new NATO reporting name Grizzly and a new DoD designation SA-17. In 2013, the latest incarnation "Buk-M3" was scheduled for production.

A naval version of the system, designed by MNIIRE Altair (currently part of GSKB Almaz-Antey) for the Russian Navy, according to Jane's Missiles & Rockets, received the GRAU designation 3S90M1 and will be identified with the NATO reporting name Gollum and a DoD designation SA-N-7C. The naval system was scheduled for delivery in 2014.
