The Sulu Archipelago (Tausug: سُوگْ‎, Jawi: كڤولاوان سولو‎, Filipino: Kapuluan ng Sulu) is a chain of islands in the Pacific Ocean, in the southwestern Philippines. The archipelago forms the northern limit of the Celebes Sea and southern limit of the Sulu Sea. The Sulu Archipelago islands are within the Mindanao island group, consisting of the Philippines provinces of Basilan, Sulu, and Tawi-Tawi; hence the archipelago is sometimes referred to as Basulta, derived from the first syllables of the three provinces.

Composed of islands, islets, cays, and more than 100 reefs, sometimes grouped in submerged old atolls, the archipelago lies off the coasts of the Philippines, Malaysia, and southern Vietnam. Named after the 19th-century British whaling captain Richard Spratly who sighted Spratly Island in 1843, the islands contain less than 200 ha (500 acres) of naturally occurring land area that is spread over hundreds of square km of the South China Sea.
