The Lingga Regency () is a group of islands in Indonesia, located south of Singapore, along both sides of the equator, off the eastern coast of Riau Province on Sumatra island. They are south of the populated Riau Archipelago, known for the industrial island of Batam and the tourist-frequented island of Bintan, although the Lingga Islands themselves are rarely visited due to the infrequent local transportation. The equator goes through the northern tip of Lingga Island, the main island in the archipelago. Administratively they form a Regency of the Riau Islands Province with an area of 2,266.77 km2 and a population of 86,244 people at the 2010 census and 98,633 at the 2020 census. The regency seat lies at Daik on Lingga Island. The population are mainly Malay, Bugis and Chinese (predominantly Hakka, Teochew and Hokkien). Name Lingga derives its name from the profile of which is shaped like the Hindu lingam, often interpreted as a phallic symbol. This mountain has three sharp teeth as peak, one of them seems to have broken off at its base, and it was immortalised by Malay poets as the symbol of durability. The poem is Pulau Pandan jauh ke tengah, Gunung Daik bercabang tiga, Hancur badan dikandung tanah, Budi yang baik dikenang juga. Nearby are the remains of the fort of Benteng Bukit Cening, overlooking the sea. The cannons are still lined up, as if they were awaiting another enemy attack.
