Isa Akhyadovich Munayev (Chechen: Мунаев Iиса, Russian: Иса Ахьядович Мунаев; born 20 May 1965, dead 2 February 2015) was a Chechen military commander who had fought for the independence of the Chechen Republic of Ichkeria fromRussia until being forced into exile in Europe around 2004.

Munayev had been a police officer in the Chechen capital of Grozny before the outbreak of hostilities with Russia. At the beginning of the Second Chechen War, in 1999, the Chechen leader, Aslan Maskhadov appointed him as a military commandant of Grozny. During the Battle of Grozny (1999–2000), Munayev organized ambushes, car bombs and mine explosions against the Russian forces. In October 2000, the Russian authorities erroneously reported that he had been killed when a group of rebels was trying to blow up a military truck. 

After the Chechen forces withdrew from the capital to the mountains, Munayev was made a brigadier general and commander of the Southwestern Front early in 2001. Having sustained a serious injury during fighting, he was forced to leave Chechnya in 2004 or 2005. He eventually established himself in Denmark, where he co-founded the Free Caucasus socio-political movement. In July 2014, during the war in Eastern Ukraine, the organization announced the formation of an "international peacekeeping battalion" of volunteers to support Ukraine in fighting against the pro-Russian insurgency. The battalion was named the Dudaev battalion after the first President of Chechnya, Dzhokhar Dudayev, and Munayev was appointed as its commander.

Munayev was killed outside of Debeltseve on the 2nd of February 2015.
