Yarralin, also known as Walangeri is a remote Aboriginal community in the Northern Territory of Australia. At the 2011 census, Yarralin had a population of 266. The community is located on the banks of the Wickham River, about 15 km (9.3 mi) west of Victoria River Downs, a major cattle station along the Buchanan Highway.
The community is diverse, with several indigenous language groups including Gurindji, Ngaringman, Bilinara and Mudburra represented among the residents of Yarralin. Archeological evidence and oral histories of the area surrounding the modern community indicate that Yarralin was (and remains) an important link in a traditional network for trade and exchange of goods and culture between indigenous peoples across the Northern Territory.
Yarralin is a service centre for the surrounding area and facilities available in the community include a school, health clinic, post office, police station, airstrip, community store and sports fields.
