Progress 12 (Russian: Прогресс 12) was a Soviet unmanned Progress cargo spacecraft, which was launched in January 1981 to resupply the Salyut 6 space station.


Progress 12 launched on 24 January 1981 from the Baikonur Cosmodrome in the Kazakh SSR. It used a Soyuz-U rocket.[2][4]

It remained in orbit until 20 March 1981, when it was deorbited. The deorbit burn occurred at 16:59 UTC.[3][5]
