Progress M (, GRAU: 11F615A55), also known as Progress 7K-TGM, is a Russian (formerly Soviet) uncrewed cargo spacecraft used to resupply space stations. It is a variant of the Progress series, developed in the late 1980s as a modernized version of the Progress 7K-TG spacecraft. Progress-M incorporated improved systems derived from the Soyuz T and Soyuz TM crewed spacecraft. The Progress M-M (GRAU: 11F615A60) introduced further upgrades, including digital flight control systems replacing earlier analog systems.

The first 43 Progress M spacecraft supported Mir, with later missions servicing the International Space Station (ISS). A total of 87 spacecraft were launched, including 67 of the Progress M variant and 30 of the upgraded Progress M-M. Two spacecraft were lost: Progress M-12M in a launch failure in August 2011, and Progress M-27M, which lost control after reaching orbit in April 2015 and reentered the atmosphere.
