The Free Papua Movement (Indonesian: Organisasi Papua Merdeka, abbreviated OPM) is an organization established in 1965 to encourage and effect the violent overthrow of the current governments in the Papua and West Papua provinces of Indonesia, formerly known as Irian Jaya[ to secede from Indonesia, and to reject economic development and modernity as well as to eliminate non-native populations in the island.

It has received funding from Gaddafi's Libya and training from the Maoist Guerrilla group New People's army, a Foreign Terrorist Organization designated by the US Department of Homeland Security.

The movement is outlawed in Indonesia, and agitating for independence for the provinces has incurred charges of treason.

Since its inception, the OPM has attempted diplomatic dialogue, conducted Morning Star flag-raising ceremonies, and undertaken militant actions as part of the Papua conflict.

Supporters routinely display the Morning Star flag and other symbols of Papuan unity, such as the national anthem "Hai Tanahku Papua" and a national coat of arms, which had been adopted in the period 1961 until Indonesian administration began in May 1963 under the New York Agreement.
