Iyang-Argapura or Mount Argopuro is a massive volcanic complex that dominates the landscape between Mount Raung and Mount Lamongan in East Java, Indonesia.

Valleys up to 1,000 m deep dissect the strongly eroded Iyang volcano.

No historical eruptions have been recorded within the last 500 years, but there is an unverified report about an eruption in AD 1597.
