Sitangkai is one of eleven (11) municipalities comprising the province of Tawi-Tawi in the Bangsamoro Autonomous Region ( BARMM ). The town is politically subdivided into nine (9) barangays, and is a part of the Lone Congressional District of Tawi-Tawi.

It is a trading and market center for the islands surrounding it, particularly the island of Sibutu which is famous for its wildlife.

Sitangkai is fondly referred to as the “Venice of Tawi-Tawi” due to the use of boats as the primary means of transportation, although footbridges connect houses on stilts from one another.

The primary sources of livelihood are fishing and farming, although there is very sparse agricultural land available. Alternative sources are seaweed farming and mat weaving by the women.
