Yalangbara is a coastal area in the East Arnhem (Miwatj) region of Australia's Northern Territory, around 35 km (22 mi) south of Nhulunbuy, the largest town in the area. It is on the country of the Rirratjingu clan of the Yolŋu people, and is one of the most significant cultural areas for the Yolŋu because of its role in the creation story of the Rirratjingu clan, based on the Djang'kawu ancestors.
In Yolŋu terminology, Yalangbara is a yaku bathala (literally "big name"), a term for a general area that comprises various named localities, comprising the area south of Yirrkala including the Yalangbara Peninsula (also known as the Port Bradshaw Peninsula or Port Bradshaw) as well as Lalawuy Bay, adjacent coastline and the nearby islands such as Wapilina Island. It covers around 210 km2 (81 sq mi) of land and coastal waters. However, the name can be applied to different areas, depending upon context; it may refer to the small beach site related to the Djang'kawu myth (see below), or the whole eastern side of the peninsula.
