Mount Kupreanof is a stratovolcano on the Alaska Peninsula, United States.

It is the largest and the northeasternmost in a group of five volcanoes opposite from Stepovak Bay.

Mount Kupreanof displays extremely strong fumarole activity and its latest eruption in 1987 produced minor steam and ash emission.
