The Uragan class was a class of monitors built for the Baltic Fleet of the Imperial Russian Navy. The ships were built to the plans of the American Passaic-class monitors, a design that was tested on a smaller scale on USS Monitor. A total of 10 ships were constructed at five different shipyards in Saint Petersburg, all entering service in 1865. The ships were among the first ironclad warships in the Russian Navy.

A monitor is a relatively small warship that is neither fast nor strongly armored but carries disproportionately large guns. They were used by some navies from the 1860s, during the First World War and with limited use in the Second World War.
