Jakarta (; Indonesian pronunciation: [dakarta] (listen)), officially the Special Capital Region of Jakarta (Indonesian: Daerah Khusus Ibukota Jakarta), is the capital and largest city of Indonesia. Lying on the northwest coast of Java, the world's most populous island, Jakarta is the largest city in Southeast Asia and serves as the diplomatic capital of ASEAN.

The city is the centre of the economy, culture, and politics of Indonesia. It has a province level status which has a population of 10,609,681 as of mid 2021. Although Jakarta extends over only 664.01 km2 (256.38 sq mi), and thus has the smallest area of any Indonesian province, its metropolitan area covers 9,957.08 km2 (3,844.45 sq mi), which includes the satellite cities Bogor, Depok, Tangerang, South Tangerang, and Bekasi, and has an estimated population of 35 million as of 2021, making it the largest urban area in Indonesia and the second-largest in the world (after Tokyo). Jakarta ranks first among the Indonesian provinces in human development index. Jakarta's business opportunities, and its ability to offer a potentially higher standard of living than is available in other parts of the country, have attracted migrants from across the Indonesian archipelago, making it a melting pot of numerous cultures.

Jakarta is one of the oldest continuously inhabited cities in Southeast Asia. Established in the fourth century as Sunda Kelapa, the city became an important trading port for the Sunda Kingdom. At one time, it was the de facto capital of the Dutch East Indies, when it was known as Batavia. Jakarta was officially a city within West Java until 1960, when its official status was changed to a province with special capital region distinction. As a province, its government consists of five administrative cities and one administrative regency. Jakarta is an alpha world city and is the seat of the ASEAN secretariat, Financial institutions such as the Bank of Indonesia, Indonesia Stock Exchange, and corporate headquarters of numerous Indonesian companies and multinational corporations are located in the city. In 2017, the city's GRP PPP was estimated at US$483.4 billion.

Jakarta's primary challenges include rapid urban growth, ecological breakdown, gridlocked traffic, congestion, and flooding. Jakarta is sinking up to 17 cm (6.7 inches) per year, which, coupled with the rising of sea levels, has made the city more prone to flooding. It is one of the fastest-sinking capitals in the world. Because of these challenges, in August 2019, President Joko Widodo announced that the capital of Indonesia would be moved from Jakarta to the planned city of Nusantara, in the province of East Kalimantan on the island of Borneo.

Indonesia ( (listen) IN-də-NEE-zhə), officially the Republic of Indonesia, is a country in Southeast Asia and Oceania between the Indian and Pacific oceans. It consists of over 17,000 islands, including Sumatra, Sulawesi, Java, and parts of Borneo and New Guinea. Indonesia is the world's largest island country and the 14th-largest country by area, at 1,904,569 square kilometres (735,358 square miles). With about 270 million people, Indonesia is the world's fourth-most populous country and the most populous Muslim-majority country. Java, the world's most populous island, is home to more than half of the country's population.

Indonesia is a presidential republic with an elected legislature. It has 34 provinces, of which five have special status. The country's capital, Jakarta, is the world's second-most populous urban area. Indonesia shares land borders with Papua New Guinea, East Timor, and the eastern part of Malaysia, as well as maritime borders with Singapore, Vietnam, Thailand, the Philippines, Australia, Palau, and India (Andaman and Nicobar Islands). Despite its large population and densely populated regions, Indonesia has vast areas of wilderness that support one of the world's highest levels of biodiversity.

The Indonesian archipelago has been a valuable region for trade since at least the 7th century when Srivijaya and later Majapahit traded with entities from mainland China and the Indian subcontinent. Local rulers gradually absorbed foreign influences from the early centuries, and Hindu and Buddhist kingdoms flourished. Sunni traders and Sufi scholars brought Islam, while Christianity was brought mostly through Europeans. Although sometimes interrupted by the Portuguese and the French and British, the Dutch were the foremost colonial power for much of their 350-year presence in the archipelago. The concept of "Indonesia" as a nation-state emerged in the early 20th century, culminating later in the proclamation of Indonesian Independence in 1945. However, it was not until 1949 that the Dutch recognised Indonesia's sovereignty following an armed and diplomatic conflict between the two.

Indonesia consists of hundreds of distinct native ethnic and linguistic groups, with Javanese being the largest. A shared identity has developed with the motto "Bhinneka Tunggal Ika" ("Unity in Diversity" literally, "many, yet one"), defined by a national language, ethnic diversity, religious pluralism within a Muslim-majority population, and a history of colonialism and rebellion against it. The economy of Indonesia is the world's 16th-largest by nominal GDP and the 7th-largest by PPP. It is a regional power and is considered a middle power in global affairs. The country is a member of several multilateral organisations, including the United Nations, World Trade Organization, G20, and a founding member of the Non-Aligned Movement, Association of Southeast Asian Nations, East Asia Summit, and the Organisation of Islamic Cooperation.
