Dulmatin (6 or 16 June 1970 – 9 March 2010) was a senior figure in the militant Islamic group Jemaah Islamiyah (JI) based in Indonesia, and one of the most wanted terrorists in Southeast Asia.

According to the Jakarta Globe, when Dulmatin was a young man he attended a religious boarding school run by the founder of the Jemaah Islamiyah, Abu Bakar Bashir.

From radio intercept and human intelligence, authorities believe that Dulmatin was wounded in a gun battle with the Philippines military in January 2007, on the southern island of Jolo.

At the beginning of 2010 Dulmatin began training a group of militants in the foothills of Jalin, just south of Banda Aceh in Indonesia in an attempt to build a 'nerve centre for Southeast Asian terrorism' under the name 'Al-Qaeda of the Verandah of Mecca.
