A Greek coast guard statement says another six people suffered light injuries on board the Cypriot-owned Louis Majesty.
It says the accident occurred near the French Mediterranean port of Marseilles as the ship was sailing from Barcelona to Genoa in Italy with 1,350 passengers and 580 crew.
The victims have been identified only as a German and an Italian man.
Louis Cruise Lines spokesman Michael Maratheftis said the ship was hit by three 'abnormally high' waves up to 26ft high that broke glass windshields in the forward section.
The cruise ship is safely heading back to Barcelona.
