Municipalities of Timor-Leste in the context of "Oecusse"

Atauro (Portuguese: Ilha de Ataúro, Tetum: Illa Ataúru, Indonesian: Pulau Atauro), also known as Kambing Island (Indonesian: Pulau Kambing), is an island and municipality (Portuguese: Município Ataúro, Tetum: Munisípiu Atauro or Ata'uro) of Timor-Leste. Atauro is a small oceanic island situated north of Dili, on the extinct Wetar segment of the volcanic Inner Banda Arc, between the Indonesian islands of Alor and Wetar. The nearest island is the Indonesian island of Liran, 13.0 km (8.1 mi) to the northeast. At the 2015 census, it had 9,274 inhabitants.

Atauro was one of the administrative posts (formerly subdistricts) of Dili Municipality until it became a separate municipality with effect from 1 January 2022.

Jaco Island (Portuguese: Ilha de Jaco, Tetum: Illa Jako, Fataluku: Totina or Tontina) is an uninhabited island in Timor-Leste, 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).

The municipalities of Timor-Leste are divided into 70 administrative posts (previously subdistricts until 2014) since 2024. On 1 January 2024, three new administrative posts were created, one in Liquiçá Municipality (Loes) and two in Baucau Municipality (Quelicai Antiga and Matebian)

Each administrative post is divided into several sucos. Sucos are divided into several aldeias, the smallest political division of East Timor.

Uab Meto or Dawan is an Austronesian language cluster spoken by the Atoni people of the Indonesian region of West Timor, as well as the East Timorese municipality of Oecussi-Ambeno.

In East Timor and other Portuguese-speaking countries the language is often called Baikenu (Portuguese: baiqueno), but more narrowly this term refers only to the variety spoken in East Timor, which is more influenced by Portuguese rather than Indonesian (for example, using obrigadu for 'thank you', instead of the Indonesian terima kasih). In other languages it may also be erroneously referred to as West Timorese (with Tetum being "East Timorese") or even just Timorese, but these terms are misleading, as they ignore the linguistic diversity on both sides of the island.
