The Isatabu Freedom Movement (IFM) was a nationalist militant organisation of the island of Guadalcanal in Solomon Islands.
The movement also included other factions such as the Guadalcanal Revolutionary Army and the Guadalcanal Liberation Front which was led by warlord Harold Keke. It was engaged in fighting against the Solomon Island Government and the Guadalcanal Provincial Government as well as with another militant organisation, Malaita Eagle Force. In response to the fighting, the government enacted the Regional Assistance Mission to Solomon Islands.
