The Balangingi, also known Northern Sama or Northern Sinama, is an ethnolinguistic group living on the Greater Sulu Archipelago and the southern and western coastal regions of the Zamboanga peninsula in Mindanao. They are mostly found in Lutangan and Olutangga islands in Zamboanga del Sur, Basilan Island of the Sulu Archipelago, coastal areas of Zamboanga coast peninsula, and as far north as Luzon, particularly in White Beach near Subic Bay, Zambales. Balangingis are considered to be part of of the larger group of Sama-Badjao and speak the Balangingi dialect. Chavacano and Tausug have influenced the Balangingi language. The majority of Balangingi speakers are Muslims and are familiar with Arabic.
Families live close to one another and are grouped into larger units called tumpuks (clusters). Some build their houses along the shoreline while others, over the sea; they are linked by narrow bridges. Balangingis are maritime people, and fishing is their main source of livelihood. Women weave mats and sell pottery, while men fish, build boats, and do iron works. They are famous for their traditional dances, percussion and xylophone music, dyed mats, and woodcarvings.
