The Ngaiawang (Ngayawang) were an Aboriginal Australian people of the western Riverland area of South Australia, with a language considered part of the Lower Murray group. They are now considered extinct. They have sometimes been referred to as part of the Meru people, a larger grouping which could also include the Ngawait and Erawirung peoples.[1][2] They were called Birta by the Kaurna and Ngadjuri peoples, variations of Murundi by the Jarildekald people, and were also known various other terms and spellings.
