Salvethymus svetovidovi, also called the long-finned charr, is a species of salmonid fish. It is endemic to Elgygytgyn Lake in Chukotka, Far East of Russia, together with another char species, the small-mouth char Salvelinus elgyticus. A third char species in the same lake is the Boganid char Salvelinus cf. boganidae.

The long-finned char is a morphologically aberrant type of char; when scientifically first described in 1990, it was placed as the single species in Salvethymus, a new monotypic genus. It is closely related to the true chars in the genus Salvelinus and is phylogeneticaclly placed within this genus; it is probably a sister lineage to the Arctic char complex (Salvelinus alpinus).
