Riñihue (Spanish pronunciation: [riˈɲiwe]) is a hamlet (Spanish: caserío) in Los Lagos, Chile. It is located south of the Tralcán Mount in the west side of Riñihue Lake. In early 20th century Riñihue grew out as a settlement due to the exploitation of wood in Riñihue Lake. Riñihue was the first Chilean lakeshore settlement to be reached by the railroad.
