East Nusa Tenggara (Indonesian: Nusa Tenggara Timur; NTT; Indonesian pronunciation: [ˌnusa təŋˌɡara ˈtimʊr], lit. 'East Southeast Islands') is the southernmost province of Indonesia. It is the eastern portion of the Lesser Sunda Islands, facing the Indian Ocean in the south and the Flores Sea in the north, with a total land area of 46,378.11 km2. It consists of some 653 islands (excluding smaller unnamed ones), with the largest ones being Sumba (10,899.41 km2 in area), Flores (15,482.42 km2), and the western part of Timor (14,079.36 km2); the latter shares a land border with the separate nation of East Timor. Also substantial in land area are Alor (2,918.75 km2) and Lembata (1,263.77 km2). The province is subdivided into twenty-one regencies and the regency-level city of Kupang, which is the capital and largest city.
Archaeological research shows that Liang Bua cave in East Nusa Tenggara has been inhabited by humans since about 190,000 years ago. The site was home to early humans, including Homo floresiensis, who were found in the cave's archaeological layers.
East Nusa Tenggara is known for its natural environment and parks, including Komodo National Park, Labuan Bajo, Lake Kelimutu and the area's beaches. The province is rich in culture, with diverse tribes, languages, and traditions such as ikat weaving and the Pasola ceremony in Sumba. East Nusa Tenggara also has a strong missionary history, seen from the majority Catholic population and is one of the two Indonesian provinces where Roman Catholicism is the predominant religion, alongside South Papua. In addition, its marine ecosystem is very rich, making it a popular destination for divers.

History
After the declaration of Indonesian independence in 1945, the eastern part of Indonesia declared the State of East Indonesia. The state was further included in the United States of Indonesia as part of the agreement with the Dutch contained in the transfer of sovereignty to Indonesia in 1949.
In 1950, United States of Indonesia dissolved itself into a unitary state and began to divide its component area into provinces. In 1958, by Indonesian law (Undang-Undang) No. 64/1958, three provinces were established in the Lesser Sunda Islands: Bali, West Nusa Tenggara and East Nusa Tenggara. These three provinces remain unaltered to the present time, although proposals for division have been considered by the Indonesian government but have been deferred due to the moratorium since 2013 on the creation of additional provinces. The area of East Nusa Tenggara province included the western part of Timor island, Flores, Sumba and many smaller islands in the region.
The province was originally (from 1958) sub-divided into twelve regencies, but on 11 April 1996, the City of Kupang, was separated from Kupang Regency and given regency-level status. Then, following the fall of the Suharto regime in 1998 and the passage of a new regional autonomy law, there was a dramatic subdividing (known as pemekaran) of regional governments across Indonesia, at both provincial and regency level. Between 1999 and 2012, nine new regencies were created in East Nusa Tenggara by the division of existing regencies:
On 4 October 1999, a new Lembata Regency (Regional code 53.13) was formed by the division of the East Flores Regency.
On 10 April 2002, Rote Island and adjacent islands were split off from Kupang Regency, to form a new Rote Ndao Regency (53.14).
On 25 February 2003, Manggarai Regency was split into two and a new West Manggarai Regency (53.15) was established.
On 2 January 2007, the administration of East Nusa Tenggara province was expanded by the establishment of three new regencies – Nagekeo (53.16) was cut out of Ngada Regency, and Central Sumba (53.17) and Southwest Sumba (53.18) were both cut out of West Sumba Regency.
Government and administrative divisions
The province is divided into twenty-one regencies and one independent city (Kupang). These are listed below with their areas and their populations at the 2010 Census and the 2020 Census, together with the official estimates as at mid 2025.
Notes: (a) includes Alor and Pantar islands. (b) East Flores Regency includes Adonara and Solor islands as well as the eastern part of Flores Island. (c) West Manggarai Regency includes Komodo and Rinca islands off the west coast of Flores.
The province has two of Indonesia's 84 national electoral districts to elect members to the People's Representative Council. The East Nusa Tenggara I Electoral District consists of the 10 regencies in the Northern (Flores) group, and elects 6 members to the People's Representative Council. The East Nusa Tenggara II Electoral District consists of the 6 regencies in the Southeastern (Timor) group and the 5 regencies in the Southwestern (Sumba) group, together with the city of Kupang, and elects 7 members to the People's Representative Council.

Geography
Located in the east of Lesser Sunda Islands, East Nusa Tenggara faces the Indian Ocean in the south and the Flores Sea in the north. This province borders East Timor (Timor-Leste) in the western part of Timor island, and is also close to the province of West Nusa Tenggara (Nusa Tenggara Barat) and the province of Maluku.
The province consists of about 566 islands, the largest and most dominant are Flores, Sumba, and the western part of Timor. The smaller islands include Adonara, Alor, Komodo, Lembata (formerly called Lomblen), Menipo, Pantar, Raijua, Rincah, Rote Island, Savu, Semau, and Solor. While Rote is the southernmost part of Indonesian territory, the Australian territory of the Ashmore and Cartier Islands, 170 kms due south from Rote, is actually much closer to that island than to any point on the Australian mainland, and they lie in zones designated for 'traditional' fishing by Indonesians.
The highest point in the province is Mount Mutis in the South Central Timor Regency, 2,427 metres above sea level. In East Nusa Tenggara, the Terumbu Karang Sehat Indonesia coral-reef programme implemented by Konservasi Indonesia has included work in East Sumba within the Savu Sea marine-national-park zoning area.
Demographics
The Census population of the province was 4,683,827 in 2010 and 5,325,566 in 2020,
Based on the latest data from the Central Statistics Agency (BPS), the population of East Nusa Tenggara Province has reached around 5.74 million people by mid 2025. Population growth in East Nusa Tenggara is at a fairly stable level, although variations in growth rates are seen in various districts and cities. Kupang City as the provincial capital is the urban area with the largest population, while the most populous regency is South Central Timor, followed by other large regencies such as Sikka and Manggarai on Flores, and Southwest Sumba.
The average population density in East Nusa Tenggara is around 110 people per km², but the population distribution is uneven. Urban areas such as Kupang City have a much higher density than rural areas spread across the outer islands, such as Alor, Rote, or Savu.
Ethnicity and religion
Ethnicity in East Nusa Tenggara consists of several main groups, including the Flores, Sumba, Timor, Rote, Alor, and Sabu peoples, foreign ethnic groups such as the Chinese, Arabs, as well as Eurasians (primarily of Portuguese and Dutch ancestry) are also present in the province. Indonesian is used as the official language in administration and education, but regional languages are still used in daily life in many local communities.
East Nusa Tenggara Province is one of the provinces in Indonesia with a majority Christian population, both Catholic and Protestant. The influence of Christianity is very strong in East Nusa Tenggara, especially in the Flores and Sumba regions, which were influenced by the arrival of European missionaries, especially from Portugal and the Netherlands. In Flores, around 85% of the population is Catholic, making it one of the areas with the largest Catholic population in Indonesia.
East Nusa Tenggara also has a significant Muslim minority, specifically in Kupang City and certain regencies such as in coastal areas or on islands such as Alor and Timor. Hinduism as well as local beliefs are also practised by a minority, especially in Sumba and Timor.
Economy
The economy of East Nusa Tenggara Province is dominated by the agriculture, fisheries, and tourism sectors. Most of the East Nusa Tenggara population works in the agricultural sector, with main crops such as corn, rice, cassava, beans, and coconuts. The livestock sector also plays an important role, especially in areas such as Sumba and Timor, where many residents raise cattle, horses, and pigs.
In addition, the fisheries sector is one of the main sources of livelihood for people in coastal areas and small islands. Fish, seaweed, and other marine products are important commodities developed by local communities.
On the other hand, the tourism sector in East Nusa Tenggara has experienced rapid development in recent years, especially with the increasing popularity of tourist destinations such as Labuan Bajo and Komodo National Park which attract tourists from within and outside the country. The area's natural environment, including its exotic beaches, volcanoes and underwater biodiversity, are the main attractions for tourists.
Economic activity
East Nusa Tenggara Province has a diverse economy with agriculture, fisheries, forestry, and cultivation as its main pillars. Subsistence farming dominates economic activity, with corn and smallholder plantation crops such as coffee being the main products. Local plants such as the lontar palm (Borassus flabellifer) and the sugar palm (Arenga pinnata) also play an important role in the local economy.
On Sumba Island, palm trees play a major role in providing wood, roofing materials, and producing food in the form of fruits and palm sugar obtained from tapping the fruit stems. In other areas such as West Manggarai, palm trees are also a source of raw materials and processed products that are useful for local communities. Products from palm and palm trees can even be processed into alcoholic beverages through traditional fermentation, which is part of the local economy.
In addition, the forestry sector also plays an important role in supporting the provincial economy. Forests in East Nusa Tenggara provide important resources such as firewood, building materials, and other non-timber products used by local communities. Forestry managed with sustainable principles not only contributes to the economy, but also helps maintain ecosystems and environmental balance, which is very important for communities that depend on natural resources.
Seaweed farming is one of the fastest growing economic sectors in coastal and island areas. In the Alor Islands, for example, informal village-based seaweed farming has become an important source of additional income for the community. Much of this seaweed is exported in its raw form to countries such as Japan, indicating greater economic potential in this sector.
Fisheries are also a mainstay sector for coastal communities. Marine products such as fish, shrimp, and various other marine products are not only a source of food for local communities but also have great potential as export products. This fisheries activity makes a significant contribution to the local economy.
Overall, the economy of East Nusa Tenggara is highly dependent on the use of natural resources traditionally managed by local communities. With agriculture, fisheries, forestry, and seaweed farming as the backbone of the economy, the province continues to develop its potential while preserving the environment and local cultural richness. Through sustainable management of natural resources, East Nusa Tenggara seeks to improve the welfare of its people and strengthen its contribution to the national economy.
Infrastructure
Although infrastructure development in East Nusa Tenggara continues to grow, the province still faces challenges in terms of inter-island connectivity. Land, sea, and air transportation continue to be improved to connect remote areas, but some areas are still difficult to reach, especially during the rainy season when road conditions become less good. On the other hand, the construction of roads, bridges, ports, and airports has been carried out in stages to improve mobility and accessibility, as well as support economic and tourism development in the province.

Education
Accessibility to education is difficult, especially in remote areas and islands, where many schools lack basic facilities such as proper buildings, laboratories, and libraries. The quality of teaching also needs to be improved due to the uneven distribution of teachers and the lack of qualified teaching staff in rural areas. Efforts to improve this sector continue to be carried out through government programs such as scholarships and the construction of new schools, although infrastructure and teaching staff challenges remain major issues.
Health
The health sector in East Nusa Tenggara sees major challenges in terms of access to and quality of health services. Many remote areas are difficult to reach, and health facilities are often inadequate with limited equipment and medicines. The shortage of medical personnel, especially in rural areas, further exacerbates this situation. Major health problems in NTT (East Nusa Tenggara) include malnutrition, high maternal and infant mortality rates, and infectious diseases such as malaria and tuberculosis. Efforts to improve the situation are being made through the construction of new health facilities, national health programs, and interventions from non-governmental organizations, although geographic and logistical challenges remain major obstacles.
Tourism
East Nusa Tenggara is a province rich in diverse tourist attractions, and the provincial government is actively working to promote tourism. Tourist hotspots include:
Komodo National Park
Kelimutu National Park on Flores, featuring three crater lakes of varying colors
Mount Mutis, east of Kupang, known as the highest point of the province
Semana Santa in Larantuka, a religious tradition celebrated annually
