Bandar Seri Begawan is the capital city of the Sultanate of Brunei. It is officially governed as a municipality. Bandar Seri Begawan has an estimated population of 100,700, and including the whole Brunei-Muara District, the metro area has an estimated population of 279,924.

'Bandar Seri Begawan' is derived from the official Malay name which is translatable as 'Seri Begawan City', with Seri Begawan being derived from Sanskrit (śrī bhagavan) meaning 'the aura of the gods'. It was named after Sultan Omar Ali Saifuddien III, who was the previous Sultan of Brunei and the late father of the current Sultan Hassanal Bolkiah.

'Seri Begawan' is part of the royal title bestowed on the late Sultan upon his abdication from the throne in 1967. The city was renamed in 1970 to commemorate his contribution to the development of the country during his reign, especially on the modernisation of Brunei in the 20th century. Prior to this, the city had been known as 'Bandar Brunei' (literally 'Brunei City') or 'Brunei Town'.
