Uzon (Russian: Узон) is a 9 by 12 km volcanic caldera located in the eastern part of Kamchatka Peninsula, Russia . Together with the Geyzernaya caldera it hosts the largest geothermal field in the Kamchatka Peninsula. The calderas were formed in the mid-Pleistocene in several large eruptions that deposited 20–25 km3 of ignimbrite over a wide area. Lake Dalny fills a Holocene maar in the northeast of Uzon Caldera.

The Uzon Caldera is a location of the occurrence of extremophile micro-organisms due to its high localized temperatures.(C.Michael Hogan. 2010)
