Mount Veniaminof is an active stratovolcano on the Alaska Peninsula. The Alaska Volcano Observatory currently rates Veniaminof as Aviation Color Code ORANGE and Volcano Alert Level WATCH as of 4 September 2018, at 2109 (UTC).[3] The mountain was named after Ioann (Ivan Popov) Veniaminov (1797–1879), a Russian Orthodox missionary priest (and later a prominent bishop in Russia) whose writings on the Aleut language and ethnology are still standard references. He is a saint of the Orthodox Church, known as Saint Innocent for the monastic name he used in later life.

The volcano was the site of a colossal (VEI 6) eruption around 1750 BC. This eruption left a large caldera. In modern times the volcano has had numerous small eruptions (over ten of them since 1930), all at a cinder cone in the middle of the caldera.

Veniaminof is one of the highest of Alaskan volcanoes. Partly for this reason, it is covered by a glacier that fills most of the caldera. Because of the glacier and the caldera walls, there is the possibility of a major flood from a future glacier run.
