Mount Veniaminof (Russian: Вулкан Вениаминова) is an active stratovolcano on the Alaska Peninsula.

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.

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.

Despite starting off as an effusive eruption, by November 20, the eruption became more intense and ash was reaching 20,000 feet, prompting the AVO to give a warning for aviation because of the ash posing a threat to aviation.

Even an ashfall warning was issued for the nearby town of Perryville.
