Bogor Regency (Indonesian: Kabupaten Bogor, Indonesian pronunciation: [kabuˌpat̪ɛn ˈbɔɡɔr]; Sundanese: ᮊᮘᮥᮕᮒᮨᮔ᮪ ᮘᮧᮌᮧᮁ, romanized: Kabupatén Bogor, Betawi: Kabupatén Bogor) is a landlocked regency (kabupaten) of West Java province in Indonesia, situated 40-50 kilometers south from the city of Jakarta as a national capital. Covering an area of 2,991.78 km², it is considered largely a bedroom community for Jakarta, and was home to 5,427,068 people at the 2020 census. The official estimate as at mid 2024 was 5,682,303 (comprising 2,912,658 males and 2,769,645 females). The town of Cibinong serves as the seat of the regency administration.

The area has witnessed significant population growth. Two areas formerly within the regency have been split off as autonomous cities; on 27 April 1999, the city of Depok was unified with some neighbouring districts of Bogor Regency to form an autonomous city of Depok (independent of the regency), while Bogor city had previously been formed as an autonomous city (similarly independent of the regency). In spite of these subtractions, Bogor Regency remains the most populous regency in Indonesia.

There are various opinions about the origin of the name Bogor itself. One opinion states that the name Bogor comes from Arabic language, namely Baqar which means cow on the grounds that there is evidence in the form of a statue of a cow in the Bogor Botanical Gardens. Another opinion states that the name Bogor comes from the word Bokor which means palm tree stump. The opinion above has its own basis and reasons for being believed to be true by each expert.

However, based on historical records, on 7 April 1752 the word "Bogor" appeared in a document and it was written as "Hoofd van de Negorij Bogor", which means Head of Kampung Bogor. In the documents it is also known that the village headquarters was located within the site of the Botanical Gardens itself, which began construction in 1817.

In 1745, the forerunners of the Bogor community originally came from 9 settlement groups with 3 combined major groups, namely Bogor (central region), Tjibaroesa/Djonggol (eastern and northern regions) and Parung (western region) which was combined by the Governor-General Dutch Indies, Baron van Inhof into the core of the Bogor Regency community unit.

At that time, the Regent of Demang Wartawangsa tried to improve the quality of the environment and the welfare of the people based on agriculture by digging canals from Ciliwung River to Cimahpar and from Nanggewer to Kalimulya.

In 1908 Bogor Regency was composed of five kawedanan each led by a demang, namely Buitenzorg, Tjibaroesa, Cibinong, Parung, and Leuwiliang. Then, to facilitate district tasks, a number of under-districts were formed, each headed by an assistant demang.

The history of Bogor Regency had a close relationship with the era of the kingdom that once ruled in the region. In the previous four centuries, Sri Baduga Maharaja was known as the king who started the era of Pajajaran Kingdom, The king was famous for the teachings of his venerated ancestors who pursued prosperity.
