Jakarta, officially the Special Capital Region of Jakarta, is the capital and largest city of Indonesia. Lying on the northwest coast of Java (the world's most populous island), it is the largest city in Southeast Asia.

Its name 'Jakarta' derives from the word Jayakarta which is ultimately derived from the Sanskrit जय jaya (victorious), and कृत krta (accomplished, acquired), thus Jayakarta translates as 'victorious deed', 'complete act' or 'complete victory'. It was named after Muslim troops of Fatahillah successfully defeated and drove out the Portuguese away from the city in 1527.

In the 17th century, the city was known as Koningin van het Oosten (Queen of the Orient), for the urban beauty of downtown Batavia's canals, mansions and ordered city layout.

During the Japanese occupation, the city was renamed as Jakaruta Tokubetsu-shi (Jakarta Special City).
