Ugashik-Peulik is a volcanic complex in the U.S. state of Alaska, which includes the stratovolcano of Mount Peulik and the adjacent Ugashik caldera.[1] It is located to the south of Becharof Lake in Lake and Peninsula Borough on the Alaska Peninsula. It is part of the Aleutian Range.

There are reports of eruptions at the complex in 1814 and 1852, but both are questionable.[2][3][4]
