Tausug (Tausug: Bahasa Sūg, Malay: Bahasa Suluk, Filipino: Wikang Tausug) is a regional language spoken in the province of Sulu in the Philippines, in the eastern area of the state of Sabah, Malaysia, and in North Kalimantan, Indonesia by the Tausūg people.

It is widely spoken in the Sulu Archipelago (Basilan, Sulu and Tawi-Tawi), Zamboanga Peninsula (Zamboanga del Norte, Zamboanga Sibugay, Zamboanga del Sur, and Zamboanga City), Southern Palawan, Malaysia (eastern Sabah) and Indonesia (North Kalimantan). Tausug and Chavacano are the only Philippine languages spoken on the island of Borneo.

The Tausug language is very closely related to the Surigaonon language of the provinces Surigao del Norte, Surigao del Sur and Agusan del Sur, and to the Butuanon language of northeastern Mindanao.
