Operation Neretva '93 was an Army of the Republic of Bosnia and Herzegovina (ARBiH) operation against the Croatian Defence Council (HVO) in September 1993 on a 200 km long front from Gornji Vakuf to south of Mostar, one of its largest of the year, during the Croat–Bosniak War. The ARBiH made limited gains in the area of northern Herzegovina and around Mostar, but did not achieve a breakthrough to the southern Neretva, where the HVO retained control. The operation was halted in October. During the operation, dozens of Croat civilians were killed in the Grabovica and Uzdol massacres.
