Bruneian Malays are a native Malay ethnic group that lives in Brunei, the federal territory of Labuan, the southwestern coast of Sabah and the northern parts of Sarawak. The Bruneian Malays are a subgroup of the larger ethnic Malay population found in the other parts of the Malay World, namely Peninsular Malaysia and the central and southern areas of Sarawak including neighbouring lands such as Singapore, Indonesia and Southern Thailand, having visible differences especially in language and culture, even though they are ethnically related to each other and follow the teachings of Islam. All Bruneian Malays who are born or domiciled in East Malaysia even for generations before or after the independence of the states of Sabah and Sarawak from the British Empire through the formation of Malaysia in 1963 are also considered Malaysian Malays in the national census and were in the same status like the Malaysian Malays domiciled in Peninsular Malaysian states and the central and southern parts of Sarawak. They are also defined as a part of the Bumiputera racial classification together as a subgroup within the Malaysian Malay ethnic population along with the Kadazan-Dusuns, Orang Ulu, Ibans, Malaccan Portuguese, Muruts, Orang Sungai, Bajau, Suluks and the Malaysian Siamese.

Labuan, officially the Federal Territory of Labuan, is an island federal territory of Malaysia. Its territory includes Labuan Island and six smaller islands, off the coast of the state of Sabah in East Malaysia. Labuan's capital is Victoria and is best known as an offshore financial centre offering international financial and business services via Labuan IBFC since 1990 as well as being an offshore support hub for deepwater oil and gas activities in the region. It is also a tourist destination for people travelling through Sabah, nearby Bruneians and scuba divers. The name Labuan derives from the Malay word labuhan which means harbour.
