The Obiekt 279, or Object 279, (Объект 279) was a Soviet experimental heavy tank developed at the end of 1959.

This special purpose tank was intended to fight on cross country terrain, inaccessible to conventional tanks, acting as a heavy breakthrough tank. It was planned as a tank of the Supreme Command Reserve.[citation needed]
