Tawi-Tawi's at-large congressional district refers to the lone congressional district of the Philippines in the province of Tawi-Tawi. The province has been represented in the country's national legislatures since 1984. It first elected a representative provincewide at-large during the 1984 Philippine parliamentary election following the restoration of provincial and city district representation in the Batasang Pambansa where Tawi-Tawi had previously been included in the regionwide representation of Western Mindanao (Region IX) for the interim parliament. The province, created by the 1973 separation of the Tawi-Tawi island group from Sulu, was formerly represented as part of that province's at-large district in earlier legislatures. Since the 1987 restoration of Congress following the ratification of a new constitution, Tawi-Tawi has been entitled to one member in the House of Representatives. It is currently represented in the 20th Congress by Dimszar M. Sali of the National Unity Party (NUP).
