Cetraria arenaria, commonly known as the sand-loving Iceland lichen, is a species of terricolous (ground-dwelling), fruticose lichen in the family Parmeliaceae. It was formally described as a new species in 1977 by the Norwegian lichenologist Ingvar Kärnefelt. The type specimen was collected in 1949 by Henry Imshaug from Mackinac County, Michigan, where he found it growing on sandy soil.
