Jemaah Islamiyah (Arabic: الجماعة الإسلامية, al-Jamāʿah al-Islāmiyyah, meaning "Islamic Congregation", frequently abbreviated JI) was a Southeast Asian Islamist militant group based in Indonesia, which was dedicated to the establishment of an Islamic state in Southeast Asia. On 25 October 2002, immediately following the JI-perpetrated 2002 Bali bombings, JI was added to the UN Security Council Resolution 1267.

JI was a transnational organization with cells in Indonesia, Singapore, Malaysia, and the Philippines. In addition to al-Qaeda, the group is also alleged to have links to the Moro Islamic Liberation Front and Jamaah Ansharut Tauhid, a splinter cell of the JI which was formed by Abu Bakar Baasyir on 27 July 2008. The group has been designated as a terrorist group by the United Nations, Australia, Canada, China, Japan, the United Kingdom and the United States. It remained very active in Indonesia where it publicly maintained a website as of January 2013.
