'''Brunei Bay''' ({{langx|ms|Teluk Brunei}}) is on the northwestern coast of [[Borneo]] island, in [[Brunei]] and [[Malaysia]]. It is located east of [[Bandar Seri Begawan]], Brunei.

It is the ocean gateway to the isolated [[Temburong District]] of Brunei, separated from the rest of Brunei by the Malaysian [[Sarawak|Sarawak State]] surrounding it to the bay.

A {{convert|30|km|adj=on}} roadway connecting the Muara and Temburong districts of Brunei, completed in 2018, crosses over the Brunei bay. The section going across the Brunei bay measures in at {{convert|14|km|adj=on}}.<ref>{{cite web|url=http://archive.bt.com.bn/news-national/2013/05/10/temburong-bridge-ready-2018|title=Temburong bridge ready 2018|last=Rabiatul|first=Kamit|date=10 May 2013|publisher=Brunei Times|access-date=10 July 2013|archive-url=https://web.archive.org/web/20131203094248/http://archive.bt.com.bn/news-national/2013/05/10/temburong-bridge-ready-2018#|archive-date=2013-12-03|url-status=dead}}</ref>

==Environment== Brunei Bay contains some 8,000 hectares of tidal [[mudflat]]s and sandflats, [[seagrass]] beds, [[coral reef]]s, [[mangrove]]s, beach forest and [[sandstone]] islets. These have been identified by [[BirdLife International]] as an [[Important Bird Area]] (IBA) because it supports significant numbers of the populations of various bird species, including [[Bonaparte's nightjar]]s, [[lesser adjutant]]s, [[Storm's stork]]s, [[Chinese egret]]s, [[greater sandplover]]s, [[spotted greenshank]]s and [[roseate tern]]s. Threats include inshore [[trawling]], [[waterbird]] hunting, and [[habitat fragmentation]] through mangrove clearance.<ref name=bli> {{cite web |url=http://datazone.birdlife.org/site/factsheet/brunei-bay-iba-brunei|title= Brunei Bay |author=<!--Not stated--> |website=BirdLife Data Zone |publisher= BirdLife International|access-date= 3 October 2020 }}</ref>
