Pavlof Sister is a stratovolcano on the Alaska Peninsula.

It is a satellite peak of Pavlof Volcano, lying directly northeast.

It is considered dormant, as the volcano was reported to have last erupted between 1762 and 1786 although the event is questionable.

[1] The Alaska Volcano Observatory has the volcano alert level of Pavlof Sister set to "Unassigned", meaning the volcano is not currently monitored.
