The Markale massacres were two massacres committed by the Army of Republic of Srpska on civilians during the Siege of Sarajevo in the Bosnian War. They occurred at the Markale (marketplace) located in the historical core of Sarajevo, Bosnia and Herzegovina.

The first happened on February 5, 1994 when 68 people were killed and 144 more were wounded. The second occurred on August 28, 1995 when a mortar shell killed 37 people and wounded another 90. This latter attack was the stated reason for NATO air strikes against the Bosnian Serb forces that would eventually lead to the Dayton Peace Accords and the end of the war in Bosnia and Herzegovina.

The question of whether the shells responsible for the massacres came from Bosnian government Army of Republic of Srpska forces positions had been the subject of a prolonged controversy and numerous conspiracy theories. However, The Bosnian government army site in question was visible to UNPROFOR (UN) observers at the time, who reported that no shell was fired from that position.
