Ivan Asen II (Bulgarian: Иван Асен II, and also Йоан Асен II, Ioan Asen II, in English sometimes John Asen II) was emperor (tsar) of Bulgaria from 1218 to 1241.

He was a son of Ivan Asen I of Bulgaria and Elena (religious name Evgenija). Elena, who survived until after 1235, is sometimes alleged to be a daughter of Stefan Nemanja of Serbia, but this relationship is questionable and would have caused various canonical impediments to marriages between various descendants. Ivan Asen II's father was one of the two founders of the Asen dynasty and the Second Bulgarian Empire. Under Ivan Asen II's rule, the empire would become the dominant force in the Balkans for about a decade, 1230-1241.

Ivan Asen II is considered, with good reason, one of the most important and successful rulers of Bulgaria. His work included the restoration of the autocephalous Bulgarian patriarchate in 1235 (after a long hiatus since 1018), the minting of the first Bulgarian non-imitation coinage in both gold and copper, the suppression of the centrifugal forces that had plagued his predecessor's reign, and the expansion of Bulgaria's frontiers in all directions.
