IPB University in the City of Bogor (or formerly Bogor Agricultural University) (Indonesian: Institut Pertanian Bogor, abbreviated as IPB; Sundanese: ᮄᮔ᮪ᮞ᮪ᮒᮤᮒᮥᮒ᮪ ᮕᮨᮁᮒᮔᮤᮃᮔ᮪ ᮘᮧᮌᮧᮁcode: sun promoted to code: su ) is a state-run agricultural university based in the regency of Bogor, Indonesia. IPB has long been considered one of the "Big 5" universities in Indonesia, along with University of Indonesia, Bandung Institute of Technology, Gadjah Mada University and Airlangga University.

The institute began as an agricultural school formed by the Dutch colonial regime in the early 20th century. After independence it was part of the University of Indonesia before becoming an independent institute on September 1, 1963.

The first school in Bogor was established in 1876 under Rudolph Scheffer, under the name Landbouwschool te Buitenzorg (Agriculture School at Buitenzorg). New schools for different fields were opened in the following years for Native Indonesians. The institute started in the early 20th century as a veterinary medicine and agricultural school. Before World War II, the institutions were known as Middelbare Landbouwschool (secondary agricultural school), Middelbare Bosbouwschool (secondary forestry school) and Nederlandsch-Indische Veeartsenijschool (The Dutch East Indies Veterinarian School). The appointment of Hermanus Johannes Lovink as Department Director of Agricultural Education in 1910 marked a curriculum shift toward training for the government and private sides of colonial agribusiness, including basic biology classes augmented with practical education about cultivation techniques and technologies. Lovink argued that department officials in the Ministry of Agriculture "needed to familiarize themselves with Javanese farming practices."

In 1940, the Dutch government founded an institution of agricultural higher education in Bogor under the name Landbouw Hogeschool, which later on 31 October 1941 was then called the Landbouwkundige Faculteit (Agronomy Faculty). However, the school was closed down during the Japanese occupation (1942-1945). The Nederlandsch-Indische Veeartsenijschool remained in operation, but its name was changed to Bogōru jūigakkō (ボゴール獣医学校) (Bogor Veterinary School).

After the declaration of independence in 1946, the Ministry of Social Welfare of the new Republic of Indonesia promoted the Veterinary School in Bogor, into the College of Veterinary Medicine (PTKH). The Netherlands returned to Indonesia and regained control of the institution in 1947, thus the Landbouwkundige Faculteit was reopened as the Faculteit voor Landbouw-Wetenschappen, which had majors in Agriculture and Forestry. In 1948, the PTKH was changed to Faculteit voor Diergeneeskunde under Universiteit van Indonesië (later the University of Indonesia).

After Indonesia gained its independence in 1950, the Faculteit voor Landbouw-Wetenschappen became the Faculty of Agriculture of the University of Indonesia, with three departments: Socio-Economics, Physical Sciences, and Forestry. In 1957, the Department of Land Fishery was then formed. Meanwhile, Faculteit voor Dieergeneeskunde became the Faculty of Veterinary Medicines and Animal Husbandry.

IPB was founded on September 1, 1963 by the decision of the Minister of Science and Higher Education No. 92/1963 and was approved by President Sukarno's decree No. 279/1965. At the time, the two faculties of University of Indonesia located in Bogor were separated into an independent institution. IPB's five initial faculties at its establishment included the Faculty of Agriculture, Veterinary Medicine, Fisheries, Animal Science, and Forestry.

On December 26, 2000 the Indonesia government changed IPB's autonomy status to a state-owned university.^{[citation needed]}
