Jabotabek (or Jabodetabek) was an official definition of the urban area surrounding the Indonesia capital city Jakarta. The definition dates from 2000 and included five municipalities and three regencies. The population of Jabotabek was 28.0 million according to the Indonesian Census 2010. As of 2012, it has been officially replaced by Jabodetabekjur, however, all metropolitan area definitions are based on the Jabodetabek definition.

The area comprises the DKI Jakarta and parts of West Java and Banten provinces, specifically the three Regencies of those provinces which surround Jakarta - Bekasi and Bogor in West Java, and Tangerang in Banten. Also included were the Kota (formerly Kotamadya) independent municipalities of Bogor, Depok, Bekasi, Tangerang and South Tangerang. It does not include the other surrounding regencies into which the built-up area has now sprawled - specifically Serang and Karawang Regencies.

The name of the region is taken from the first two or three letters of each city's name: Jabo(de)tabek from Jakarta, Bogor, (Depok), Tangerang and Bekasi.

Jakarta ( /dʒəˈkɑrtə/), officially known as the Special Capital Territory of Jakarta (Indonesian: Daerah Khusus Ibu Kota Jakarta), is the capital and largest city of Indonesia. Located on the northwest coast of Java, Jakarta is the country's economic, cultural and political centre, and with a population of 10,187,595 as of November 2011, it is the most populous city in Indonesia and in Southeast Asia, and is the twelfth-largest city in the world. The official metropolitan area, known as Jabodetabekjur, is the second largest in the world, yet the city's suburbs still continue beyond it. Jakarta is listed as a global city in the 2008 Globalization and World Cities Study Group and Network (GaWC) research. and has an area of 661 square kilometres (255 sq mi)

Based on Brooking Institute survey about growth, in 2011 Jakarta ranked 17th among the world's 200 largest cities, a significant jumps from 2007 when Jakarta ranked 171st. Jakarta has seen more rapid growth than Kuala Lumpur, Beijing and Bangkok.

Greater Jakarta (Indonesian: Jakarta Raya) is the urban agglomeration surrounding Jakarta, Indonesia, the capital and largest city in the country. There are multiple definitions, all of which rank Greater Jakarta among the largest urban agglomerations on the planet.

Jakarta and Greater Jakarta in general, are home to people from all over the country, as well as a sizeable expatriate population. Like Jakarta, significant numbers of Bataks reside in Greater Jakarta, along with native and majority Sundanese as well as Javanese from the rest of the island.

The definition of Jabodetabek is the basis for all metropolitan area definitions, however, it is now an old definition.

As Greater Jakarta continued its rapid growth and sprawl over the decades, definitions are modified and municipalities (kota) coalesced out of regencies. Names grow longer as syllables of cities are tacked on the ends. Initially, the metropolitan area was defined as:

Furthermore, as the region is densely populated and large cities lie just outside even this definition, the following table has been provided:
