Brunei at the 2000 Summer Olympics

Brunei, as Brunei Darussalam, competed at the 2000 Summer Olympics in Sydney, Australia, which were held from 15 September to 1 October 2000. The country's participation in Sydney marked its second competing appearance at the Summer Olympics since its debut in 1996. The athlete delegation of the nation consisted of two athletes: sprinter Haseri Asli and shooter Prince Abdul Hakeem Jefri Bolkiah.

Asli was the first athletics competitor to compete for Brunei at the Olympics and was designated the flagbearer for the opening ceremony. He competed in the heats of the men's 100 metres though did not advance further. Making his second appearance, Hakeem competed in the qualification round of the men's skeet and also did not advance further. Thus, Brunei has yet to win an Olympic medal.
