Fuss Peak (Russian: Вулкан Фусса; Japanese: 後鏃岳; Shiriyajiri-dake) is an active stratovolcano located on the southwest coast of Paramushir Island, Kuril Islands, Russia.

The volcano was discovered in 1805 during the first Russian circumnavigation of the Earth and named in honor of a Swiss mathematician Nicolas Fuss, who served as the permanent secretary to the Academy of Sciences in St. Petersburg.

Only one unambiguous eruption, in 1854, is known.

Fuss Peak is still active.
