Salmo lumi is a type of trout, a fish in the Salmonidae family. It is endemic to Lake Ohrid and its tributaries in Albania and Macedonia. Salmo lumi is one of four different forms of the Ohrid trout complex within Lake Ohrid, along with Salmo letnica, Salmo balcanicus and Salmo aphelios. There are however no known morphological characters that would clearly distinguish it from the others. The head and body of these trout are silver in colour, with black dots. Red dots occur along the lateral line. Salmo lumi can grow to 38 cm length.
