West Java

West Java (Indonesian: Jawa Barat, Sundanese: ᮏᮝ ᮊᮥᮜᮧᮔ᮪, romanized: Jawa Kulon) is an Indonesian province on the western part of the island of Java, with its provincial capital in Bandung and its largest city is Bekasi. West Java is bordered by the province of Banten and the country's capital region of Jakarta to the west, the Java Sea to the north, the province of Central Java to the east and the Indian Ocean to the south. With Banten, this province is the native homeland of the Sundanese people, the second-largest ethnic group in Indonesia.

West Java was one of the first eight provinces of Indonesia formed following the country's independence proclamation and was later legally re-established on 14 July 1950. In 1960, the city of Jakarta was split off from West Java as a 'special capital region' (Daerah Khusus Ibukota), with a status equivalent to that of a province, while in 2000 the western parts of the province were in turn split away to form a separate Banten province.

Even following these split-offs, West Java is by far the most populous province of Indonesia with a population of 48,274,162 as of the 2020 Census, which grew to 50,759,003 at mid 2025 according to the official estimates; the population continues to grew at about 400,000 per year, having surpassed the 50 millions milestone during late 2023. The province's largest cities, Bekasi (a satellite city within the Jakarta metropolitan area), Bandung and Depok (the latter also within the Jakarta metropolitan area), are the third, fourth and sixth most populous cities in Indonesia respectively. Bandung is also one of the most densely populated cities proper in the world.
