The Lake Radonjić massacre or the Massacre at Lake Radonjić refers to the mass murder of at least 34 Kosovo Serb, Kosovo Albanian and Roma civilians near Lake Radonjić, by the village of Glodjane, in Kosovo, Federal Republic of Yugoslavia on 9 September 1998. The massacre took place during the Kosovo War.

The Kosovo Liberation Army was an ethnic Albanian separatist militia that sought the separation of Kosovo, the vast majority of which is inhabited by Albanians, from the Federal Republic of Yugoslavia (FRY) and Serbia during the 1990s. Albanian nationalism was a central tenet of the KLA and many in its ranks supported the creation of a Greater Albania, which would encompass all Albanians in the Balkans, stressing Albanian culture, ethnicity and nation.
