The Protefs class (referred to as the Proteus class in some sources) was a group of submarines built for the Hellenic Navy in the late 1920s. The boats were built to a Loire-Simonot design in France and were larger than the preceding Katsonis class built by a different French company.

Four boats were built, all were named after sea gods from Greek mythology.
