The Istana Nurul Iman is the official residence of the Sultan of Brunei, Hassanal Bolkiah, and the seat of the Brunei government. The palace is located on a leafy, riverside sprawl of hills on the banks of the Brunei River, a few kilometres southwest of Bandar Seri Begawan, Brunei's capital city. The palace is often at the centre of state occasions and royal hospitality.

An official residence is a residence designated by an authority and assigned to an official, and may not always be the same place where the office holder conducts their official functions or lives.
