The Islamic Liberation Front of Patani (Malay: Barisan Islam Pembebasan Patani, abbreviated BIPP), until 1986 known as the National Liberation Front of Patani (NLFP; Malay: Barisan Nasional Pembebasan Patani, BNPP; also translated as "Patani National Liberation Front" or "National Front for the Liberation of Pattani"; Thai: ขบวนการแนวร่วมปลดแอกแห่งชาติปัตตานี) is a militant Islamic separatist movement based in northern Malaysia and with a history of operations in the South Thailand insurgency.

The group was formed in 1959 by Tengku Abdul Jalal, aka Adul na Saiburi,[8] and is reputed to be one of the first armed insurgent outfits in the Pattani area.

It renamed itself to "Islamic Front for the Liberation of Pattani" (BIPP) in 1986.

The renewed group has reduced its nationalistic emphasis and expanded its hard-line Islamic politico-religious goals.

It is known for its attacks against the Buddhist minorities of Southern Thailand.
