Timor-Leste Map

Timor-Leste, also known as East Timor, occupies the eastern half of the island of Timor, near the eastern end of the Lesser Sunda chain and across the Timor Sea from northern Australia. Its 14,874 square kilometers include three pieces beyond the main territory: Oecusse, an enclave on the north coast of Indonesian West Timor; Atauro island, about 25 kilometers north of Dili; and the small, uninhabited island of Jaco off the eastern tip. The 2022 census counted 1.34 million people, and the UN puts the total at about 1.4 million (UN World Population Prospects, 2025 estimate), one of the youngest populations in Asia.

Mountains and two coasts

Unlike most of its neighbours in the island chain, Timor is not volcanic: it was pushed up as the Australian continental plate collided with the Banda Arc, and a rugged mountain spine runs the length of the country. The highest peak, Mount Ramelau (Tatamailau), reaches about 2,986 meters, and pilgrims climb before dawn to the statue of the Virgin Mary on its summit. The north coast around Dili and Baucau lies in a rain shadow and is dry and brown for much of the year, while the south coast facing the Timor Sea is wetter, with broader plains around Suai and Viqueque. Deep straits on either side of Atauro carry strong currents between the Pacific and Indian oceans, and surveys around the island have recorded some of the highest reef fish diversity measured anywhere. Nino Konis Santana National Park, at the eastern tip, protects reefs, forest and Jaco island.

Seasons and when to visit

The northwest monsoon brings the wet season from about December to April, when heavy rain often closes mountain roads. The south coast has a second rainy spell around May to July. The dry season from May to November is the best time to visit the north coast and the mountains, and in the late dry season, around October and November, migrating whales, including blue whales, pass through the deep waters between Dili and Atauro.

Municipalities

The country has 14 municipalities. Twelve are on the main part of the island: Aileu, Ainaro, Baucau, Bobonaro, Cova Lima, Dili, Ermera, Lautem, Liquiçá, Manatuto, Manufahi and Viqueque. Atauro, previously part of Dili, became a municipality in its own right in 2022, and Oecusse is a Special Administrative Region with its own authority and a special economic zone. Dili municipality holds about a quarter of the population, some 324,000 people at the 2022 census.

Main towns

• Dili - the capital and only large city, on a sheltered bay of the north coast, with the government palace, the main port and the international airport; the Cristo Rei statue stands on a headland east of the town.
• Baucau - the second town, on a plateau above the north coast, with a Portuguese-era old town and the country's longest runway at a former military airfield.
• Maliana - capital of Bobonaro, in a rice-growing valley close to the West Timor border.
• Suai - on the south coast in Cova Lima, the planned supply base of the Tasi Mane petroleum development corridor.
• Pante Macassar - the main town of Oecusse, near Lifau, the first Portuguese settlement on Timor.
• Lospalos - the main town of Lautem in the far east, and the gateway to Nino Konis Santana National Park.

From Portuguese Timor to ASEAN's 11th member

The division of the island is a colonial legacy: Portugal held the east and Oecusse, the Netherlands the west, and treaties in 1859 and 1914 fixed the border that Indonesia later inherited. After Portugal's 1974 revolution, Fretilin declared independence on 28 November 1975; Indonesia invaded nine days later and annexed the territory, a step the UN never recognised. The territory's truth commission later estimated that at least 100,000 people died as a result of the conflict during the occupation. In a UN-organised referendum in August 1999, 78.5% of voters chose independence; militia violence followed until an Australian-led international force restored order, and after a period of UN administration the country became independent on 20 May 2002, the first new sovereign state of the 21st century.

Tetum and Portuguese are the official languages, Indonesian and English are working languages, and about 97% of the population is Catholic, which makes Timor-Leste and the Philippines Asia's two Catholic-majority countries. The US dollar is the currency, and coffee from the hills of Ermera is the main export other than oil and gas. Petroleum revenue from the Timor Sea has funded most state spending through the Petroleum Fund, but the Bayu-Undan field is near the end of production, and the larger Greater Sunrise field, whose revenue sharing was set in a 2018 maritime boundary treaty with Australia, has not yet been developed. Timor-Leste joined the World Trade Organization in 2024 and was admitted as ASEAN's 11th member on 26 October 2025 at the summit in Kuala Lumpur, the bloc's first enlargement since Cambodia joined in 1999.
