Salvelinus inframundus, also known as Orkney charr is a cold-water fish in the family Salmonidae.
This species is known from specimens fished in Heldale Water, Hoy Island, Orkney, Scotland. It is considered locally extinct there since 1908 though.
This rare char could be considered a threatened species. It has been found recently in Loch Mealt, on the Isle of Skye.
Since the impact of Canadian Arctic char fish farming in the loch upon the native char population is unknown and the taxonomic identity of the char deemed as Salvelinus inframundus is lacking essential information, a full IUCN Red List assessment cannot be made and the species is considered Data Deficient.
