Uninhabited island in East Timor

Jaco Island (Ilha de Jaco, , Fataluku: Totina or Tontina) is an uninhabited island in East Timor, a country occupying the eastern end of the island of Timor in the Lesser Sunda Islands in Southeast Asia. It lies off the eastern tip with Cape Cutcha of the island of Timor (Aldeia Pitileti, Suco Tutuala, administrative post Tutuala, municipality Lautém).

Jaco is made of limestone formed from coral. Limestone cliffs and coral reefs surround the densely forested island, which is part of the Nino Konis Santana National Park. Jaco Island lies just off the eastern end of the island of Timor, part of the Tutuala subdistrict in Lautém District, and is separated from the mainland in front of Valu Beach by a channel or strait (known as Jaco Strait) navigable by small vessels. Jaco is regarded as sacred by the local population because the beach and the channel are sometimes said to be the points where Timor Sea (Tasi Mane, the men's sea) meets the boundary between the Banda Sea (Tasi Feto, the women's sea) including Wetar Strait to the north and Timor Sea to the south. According to the standard work Limits of Oceans and Seas, 3rd edition (1953), published by the International Hydrographic Organization (IHO), however, the only point where Timor meets those two seas is Tanjong Sewirawa (now known as Cape Cutcha), the eastern extremity of the Timorese mainland. Cape Cutcha is a short distance northwest of the island, and north of the beach. At least three places on the island have the remains of ancient fortifications built by the local population to protect settlements: Lai Vai, Pitilete and Honolati. In Portuguese, such fortifications are called tranqueira (English: cover, entrenchment). The only modern structure on the island was a lighthouse from the Indonesian occupation period, a white scaffold tower about 35 m high. It was shut down in 2010 and later dismantled. The island is low lying, with an area of and a maximum elevation of about It is covered mainly by tropical dry forest, fringed by strand vegetation and white sandy beaches. There are some low cliffs on the southern coast. The East Timorese warship NRTL Jaco is named after the island.

The average annual temperature is roughly On average the island receives of rain and the north and east coast of the small island is somewhat drier.

Jaco is listed by BirdLife International as an Important Bird Area. The island supports populations of bar necked cuckoo doves, black cuckoo doves, pink headed imperial pigeons, streak breasted honeyeaters, fawn breasted whistlers, blue cheeked flowerpeckers, flame breasted sunbirds and Timor sparrows. Rare birds such as the great cuckoo dove ( Macropygia magna ) and the orpheus fathead ( Pachycephala orpheus ) live on the island, which is around 8 km2 in size and up to 100 meters high. Javan rusa ( Rusa timorensis ) are also found here which have become accustomed to drinking salt water due to the island's lack of fresh water. The beaches in the southeast are used by sea turtles to lay their eggs. Reptiles living on the island include Smooth night skinks and Forest skinks. In the surrounding waters, you can observe whales and dolphins as well as numerous species of fish.
