The Bellone class was a group of three submarines built for the French Navy during World War I.

Two of these three ships, the Gorgone and the Hermione, served in the Adriatic during World War I.

The third ship, the Bellone, operated in the Atlantic during that time.

[1] As of 1935, all three ships were in the French Mediterranean Fleet, and during that year were stricken (i.e. removed from the naval register).
