Ismail Samani Peak (Russian: Pik Imeni Ismaila Samani, Tajik: Qullai Ismoili Somoni) is the highest mountain in Tajikistan and in the former Soviet Union.

When the existence of a peak in the Soviet Pamir Mountains higher than Lenin Peak was first established in 1928, the mountain was tentatively identified with Garmo Peak; but as the result of the work of further Soviet expeditions, it became clear by 1932 that they were not the same, and the new peak was named Stalin Peak (Pik Stalina, пик Ста́лина), after Joseph Stalin.

In 1962, the name was changed to Communism Peak (Pik Kommunizma, пик Коммуни́зма), and in 1998 to its current name.

The first ascent was made in 1933 by the Soviet mountaineer Evgeny Abalakov.

There are glaciers at Islamil Samani Peak.
